== General definitions ==
The meaning of the term "romantic love" has changed considerably throughout history, making it difficult to easily define without examining its cultural origins. The term is used with multiple definitions by academics.<ref name="tallis-define">{{harvnb|Tallis|2005|pp=87-88, 106}}: "The cultural history of 'romance' and various meanings of the word 'romantic' make it extremely difficult to define 'romantic love'. Academic psychology—usually quite pedantic about its terminology—has been unable to establish a consensus. Some psychologists use the term in accordance with its courtly origins, whereas others use it interchangeably with 'passionate love'. As a culture, we seem to have settled on the latter usage, viewing 'romantic love' and 'falling in love' as much the same thing."</ref><ref name=":0">{{Harvard citation no brackets|Karandashev|2017|p=xi–xiii, 35–38}}</ref> In [[Western culture]], the term may be used indiscriminately to refer to almost any attraction between men and women or which includes a sexual component ([[heterosexual]], [[homosexual]], or otherwise), although "romance" and "love" are distinguishable concepts.<ref>{{Harvard citation no brackets|Johnson|2013|pp=43-44, 102-103}}</ref><ref>{{harvnb|Diamond|2008|pp=216-217}}</ref><!-- Note: Johnson uses the actual phrase "man and woman" in his text, so Diamond's source is cited to include a modern understanding of sexual and romantic orientation in this idea.

The word "romance" is derived from the [[Latin]] word ''Romanus'', meaning "Rome" or "Roman". In the modern day, the word is used with multiple connotations, but its history has a connection to the telling of love stories. After the fall of the [[Roman Empire]], a Latin adverb ''Romanice'' (from ''Romanus'') became used to mean "in the vernacular" to identify languages which were derivatives of Latin, when Latin itself was used in more formal contexts at the time. In [[Old French]] (one of the Latin derivatives), this later became ''romans'' or ''romanz'', which referred both to the language itself, and also to works composed in it. In the [[Middle Ages]], this ''romans''/''romanz'' took on a meaning as referring specifically to a type of narrative verse about [[chivalry]] and love (called [[chivalric romance]]).<ref name=":16">{{Cite web |title=Ah, 'Romance': A Word Borne to English on the Breastplates of Chivalry |url=https://www.merriam-webster.com/wordplay/ah-romance-a-word-borne-to-english-on-the-breastplates-of-chivalry |url-status=live |archive-url=https://web.archive.org/web/20250322005000/https://www.merriam-webster.com/wordplay/ah-romance-a-word-borne-to-english-on-the-breastplates-of-chivalry |archive-date=22 March 2025 |access-date=24 August 2025 |website=[[Merriam-Webster]] |language=en}}</ref><ref name="burgess-chivalric-romance">{{Cite web |last=Burgess |first=Adam |date=12 May 2025 |title=Medieval Chivalric Romance |url=https://www.thoughtco.com/the-medieval-chivalric-romance-740720 |access-date=8 October 2025 |website=ThoughtCo |language=en}}</ref> Some of the earliest literature containing themes considered "romantic" in a more modern sense was written by [[France|French]] poets known as [[Troubadour|troubadours]]—exploring a kind of thematic love for a "cold, cruel mistress".<ref>{{Harvard citation no brackets|Johnson|2013|p=147}}</ref><ref>{{Harvard citation no brackets|Tallis|2005|p=93}}</ref><ref name="Karandasehv-88" /> These poets, like [[Chrétien de Troyes]], were being encouraged by royalty to compose works exemplifying certain ideals (now called "[[courtly love]]"),{{NoteTag|The term "courtly love" (French: "amour courtois") was coined by the French medievalist [[Gaston Paris]], in 1883.<ref name="singer-paris">{{harvnb|Singer|2009|p=19–22}}</ref><ref name="Karandasehv-88">{{harvnb|Karandashev|2017|p=88}}</ref>}} principally in the town of [[Poitiers]], where [[Andreas Capellanus]] also came to write [[De amore (Andreas Capellanus)|''The Art of Courtly Love'']].<ref>{{Harvard citation no brackets|Tallis|2005|pp=93-95}}</ref> Courtly love then became emphasized as a theme for chivalric romance.<ref name="Karandasehv-88"/><ref name="burgess-chivalric-romance"/>

{{Further|Biology of romantic love#Definition of romantic love}}
Bode & Kushnick undertook a comprehensive review of romantic love from a [[Biology|biological]] perspective in 2021. They considered the [[psychology]] of romantic love, its mechanisms, development across the lifespan, functions, and evolutionary history. Based on the content of that review, they proposed a biological definition of  romantic love:<ref name="prox-ult"/>

<blockquote>Romantic love is a [[Motivation|motivational state]] typically associated with a desire for long-term mating with a particular individual. It occurs across the lifespan and is associated with distinctive cognitive, emotional, behavioral, social, genetic, neural, and endocrine activity in both sexes. Throughout much of the life course, it serves [[mate choice]], [[courtship]], [[Sexual intercourse|sex]], and [[pair-bonding]] functions. It is a suite of adaptations and by-products that arose sometime during the recent evolutionary history of humans.</blockquote>

Lee has stated that the elements of romantic love may actually correspond to several of his love styles: eros ([[Eros (concept)|erotic love]], or love of beauty), mania (compared to [[limerence]], [[obsessive love]] or [[love addiction]]), and ludus (game-playing, non-committal love).<ref>{{Harvard citation no brackets|Lee|1973|pp=92-93, 195-196}}</ref><ref name=":18">{{Harvard citation no brackets|Tallis|2005|pp=42–43, 93}}</ref><ref>{{Harvard citation no brackets|Hatfield|Walster|1985|pp=38-39}}</ref><ref>{{Harvard citation no brackets|Lee|1988|p=46}}</ref> Of these, eros and mania most correspond to the experience of [[Falling in love|"falling" in love]].<ref>{{Harvard citation no brackets|Hendrick|Hendrick|2006|pp=154-155}}</ref> A manic lover falls in love with somebody inappropriate in many cases (a stranger, or even somebody they don't actually like), and tends to experience relationship difficulties.<ref>{{Harvard citation no brackets|Lee|1988|pp=45-46}}</ref><ref>{{Harvard citation no brackets|Lee|1998|p=37}}</ref><ref>{{Harvard citation no brackets|Lee|1973|pp=91-92, 97-104}}</ref> Mania is most closely compared to eros, the romantic style in search of an ideal physical type.

* [[Intrusive thought|intrusive thoughts]] and constant [[Fantasy (psychology)|fantasizing]] about the limerent object.
* uncertain reciprocation intensifying the feeling and causing emotional volatility.

According to Tennov's research, limerence is normal (despite being a madness); however, she also encountered people who had not experienced it (whom she calls "nonlimerent") and were in fact unaware the stories depict a real phenomenon.<ref>{{Harvard citation no brackets|Tennov|1999|pp=x, 13–16, 89–90, 110–111, 116–118, 161, 180,}}</ref><ref name=":18" /><ref>{{Cite book |last1=Aron |first1=Arthur |author-link1=Arthur Aron |url=https://books.google.com/books?id=8KePQgAACAAJ |title=Love and the Expansion of Self: Understanding Attraction and Satisfaction |last2=Aron |first2=Elaine |author-link2=Elaine Aron |date=1986 |publisher=Hemisphere Publishing Corporation |isbn=978-0-89116-459-3 |pages=58–59 |language=en}}</ref> Tennov indicated limerence may be experienced by 50% of women and 35% of men,<ref>{{Harvard citation no brackets|Tennov|1999|pp=209–210}}</ref> and a 2025 survey found that 64% of people had experienced it and 32% "found it so distressing that it was hard to enjoy life".<ref>{{harvnb|Bellamy|2025|p=80}}</ref> In Tennov's conception, limerence can be reciprocated and result in a [[Intimate relationship|relationship]], but there must be obstacles (as in [[Romeo and Juliet|''Romeo and Juliet'']]) for a mutual preoccupation to intensify.<ref>{{Harvard citation no brackets|Tennov|1999|pp=20–22, 44, 46, 55–57, 129}}</ref><ref name="Hayes" />

On that basis, passionate love was documented in 88.5% of cultures. For the other 11.5%, the authors believed the lack of record was probably due to ethnographic oversight rather than a genuine absence. It is therefore argued that although not everyone [[Falling in love|falls in love]], it is the case that in almost every culture some people do, even in those cultures where romantic love is muted or repressed.<ref name="jankowiak-fischer" />

Nevertheless, more and more voices emerged to condemn free love/free sex as the threat to social mores. Political ideologues called for a total commitment to the nation by subordinating the romantic love to imperative of revolution. The attitudes toward love and sex became conservative and restrictive. In the People's Republic of China, established in 1949, Communist officials imposed strong controls on love and 'inappropriate' sexual activity. A puritanical sexual 'primness' became definitely established.

In [[Behavioural genetics|behavioral genetics]], one tool which is valuable for determining [[Genetic influences|genetic influence]] is the [[twin study]], which compares identical [[Twin|twins]] (monozygotic, who are genetically identical) and fraternal twins (dizygotic, who are only 50% genetically related, like other [[Sibling|siblings]]). The differences between the two types of twins are used to estimate how much of a given trait is [[Heritability|heritable]] (how much the individual differences in a group, i.e. [[variance]], can be accounted for by genetic differences between individuals), and how much is environmental. Environmental contribution is further split between shared environment (which makes family members more similar) and nonshared environment (which makes them different, but for mathematical reasons also includes measurement error).<ref>{{Harvard citation no brackets|Plomin|DeFries|McClearn|McGuffin|2000|pp=75-82, 85, 87, 169, 296-301, 329-331}}</ref> A twin study has investigated genetic and environmental influences using the ''Love Attitudes Scale'', developed to measure Lee's love styles.<ref name=":9" /><ref>{{Harvard citation no brackets|Hendrick|Hendrick|2006|pp=149-150, 152}}: "[Lee] complained about the ahistorical nature of [most research based on his ideas] and the limited information that he felt could be derived from a rating scale: "There are no satisfactory shortcuts[.] Only elaborate instruments such as the Love Story Card Sort can distinguish between [rich] ideologies[.]" [...] Needless to say, Lee lost his argument against the use of rating scales.

The intensity of romantic love—why we become "fools for love"—can also be explained using the [[handicap principle]], which solves a contention between "honest" and "fake" [[Signalling theory|signaling]].<ref name="pinker-handicap">{{harvnb|Pinker|2009|pp=414-419, 500-501, 641}}</ref><ref name="bellamy-handicap">{{harvnb|Bellamy|2025|pp=96-97}}</ref> When real [[Emotion|emotions]] evolve, a niche is created for sham emotions which are less risky to express (like fake [[Facial expression|facial expressions]]). An honest signal can evolve without becoming worthless (because of competing fakers) only if it's ''too expensive'' to fake. One example in nature is the [[Peacock Tail|peacock's tail]]: a cumbersome display which consumes nutrients. Only a healthy peacock can afford it, so it may have evolved ''because'' it was a handicap, signaling health to females of the species. According to the [[psychologist]] [[Steven Pinker]], the way to a person's heart is to declare you're in love "because you can't help it", so romantic love might have evolved to signal true commitment.<ref name="pinker-handicap" />

[[Marriage]] as a cultural practice may only be about 4,350 years old, and historically it did not exist to bind couples for love or companionship.

Susan & [[Clyde Hendrick]] studied college students in 1993, and found that a friendship love style was more common than they anticipated. When asked to write about their closest friendship, 44% of participants spontaneously wrote about their [[significant other]]. The [[Colour wheel theory of love#Storge|storge]] [[Colour wheel theory of love|love style]] (friendship love) was also the most common love style among people who were asked to tell a story about the relationship they're currently in. The Hendricks believe their data suggests that friendship can be present as a component in the early stage of a relationship for many couples (rather than developing more slowly), and can actually precede love feelings in some cases.<ref>{{Cite journal |last1=Hendrick |first1=Susan S. |last2=Hendrick |first2=Clyde |author-link2=Clyde Hendrick |date=August 1993 |title=Lovers as Friends |url=https://journals.sagepub.com/doi/10.1177/0265407593103011 |journal=Journal of Social and Personal Relationships |language=en |volume=10 |issue=3 |pages=459–466 |doi=10.1177/0265407593103011 |issn=0265-4075|url-access=subscription }}</ref>

In 2016, Victor de Munck and David Kronenfield proposed a cultural model for romantic love in the [[United States]], developed with studies of people in [[upstate New York]] and [[New York City]].<ref name="romantic-love-us" /> The authors believe the cultural model is used as a reference standard for relationships by their informants: "People do not fit the model as much as our model can be used to explain and predict what people think, feel, and do." The American model "is unique in that it combines passion with comfort and friendship": "For successful romantic love relations, a person would feel excited about meeting their beloved; make passionate and intimate love as opposed to only physical love; feel comfortable with the beloved, behaving in a companionable, friendly way with one’s partner; listen to the other’s concerns, offering to help out in various ways if necessary; and, all the while, keeping a mental ledger of the degree to which altruism and passion are mutual." It's not claimed by the authors that everyone holds this model or that everyone opts for this type of relationship, only that the model is common or prototypical and most people know it at least implicitly. The model is tested with two case studies of informants who describe their difficulties finding a partner who meets all of these different criteria (passion, plus comfort and friendship).<ref name="romantic-love-us">{{cite journal |last1=de Munck |first1=Victor C. |last2=Kronenfeld |first2=David B. |date=1 January 2016 |title=Romantic Love in the United States: Applying Cultural Models Theory and Methods |journal=SAGE Open |volume=6 |issue=1 |pages=215824401562279 |doi=10.1177/2158244015622797 |doi-access=free}}</ref>

In his 2008 book, British writer [[Iain King]] tried to establish basic rules for the early stage of romance, as an improvement over the old maxim "all's fair in love (and war)". He concludes on six initial rules, inspired by what he calls the "Help Principle", which he argues is one good basis for a mutual relationship: "''Help someone if your help is worth more to them than it is to you.''"<ref>{{Cite book |last=King |first=Iain |author-link=Iain King |url=https://books.google.com/books?id=S6TAjY609aAC |title=How to Make Good Decisions and Be Right All the Time: Solving the Riddle of Right and Wrong |date=2008-12-16 |publisher=A&C Black |isbn=978-1-84706-347-2 |pages=78, 153, 154 |language=en}}</ref>

[[File:Eros bow Musei Capitolini MC410.jpg|thumb|upright|Roman copy of a Greek sculpture by [[Lysippus]] depicting [[Eros]], the Greek personification of romantic love]]

=== Plato ===
Greek philosophers and authors have had many theories of love. Some of these theories are presented in [[Plato]]'s ''Symposium''.{{Primary source inline|date=August 2025}} Six Athenian friends, including [[Socrates]], drink wine and each give a speech praising the [[deity]] [[Eros]]. When his turn comes, [[Aristophanes]] says in his [[myth]]ical speech that sexual partners seek each other because they are descended from beings with spherical torsos, two sets of human limbs, genitalia on each side, and two faces back to back. Their three forms included the three permutations of pairs of gender (i.e. one masculine and masculine, another feminine and feminine, and the third masculine and feminine) and they were split by the gods to thwart the creatures' assault on heaven, recapitulated, according to the comic playwright, in other myths such as the [[Aloadae]].<ref>''Symposium 189d ff''.</ref>

This story is relevant to modern romance partly because of the image of reciprocity it shows between the sexes.{{Original research inline|date=August 2025}} In the final speech before [[Alcibiades]] arrives, [[Socrates]] gives his encomium of love and desire as a lack of being, namely, the being or form of [[beauty]].

=== Arthur Schopenhauer ===
The process of courtship contributed to [[Arthur Schopenhauer]]'s pessimism, despite his own sexual success,<ref>''Essays and Aphorisms''</ref>{{Original research inline|date=October 2025}} and he argued that to be rid of the challenge of courtship would drive people to suicide with boredom. Schopenhauer theorized that individuals seek partners looking for a "complement" or completing of themselves in a partner, as in the [[cliché]] that "opposites attract", but with the added consideration that both partners manifest this attraction for the sake of the species:

<blockquote>But what ultimately draws two individuals of different sex exclusively to each other with such power is the will-to-live which manifests itself in the whole species, and here anticipates, in the individual that these two can produce, an objectification of its true nature corresponding to its aims.
—''World as Will and Representation'', Volume 2, Chapter XLIV<ref>Schopenhauer, A. (n.d.). The World as Will and Representation. https://antilogicalism.com/wp-content/uploads/2017/07/schopenhauer-the-world-as-will-and-representation-v2.pdf {{Webarchive|url=https://web.archive.org/web/20210625000705/https://antilogicalism.com/wp-content/uploads/2017/07/schopenhauer-the-world-as-will-and-representation-v2.pdf |date=2021-06-25 }}.</ref> </blockquote>

=== Other philosophers ===
{{unreferenced section|date=July 2018}}
Later modern philosophers such as [[François de La Rochefoucauld (writer)|La Rochefoucauld]], [[David Hume]] and [[Jean-Jacques Rousseau]] also focused on [[morality]], but desire was central to French thought and Hume himself tended to adopt a French worldview and temperament. Desire in this milieu meant a very general idea termed "the passions", and this general interest was distinct from the contemporary idea of "passionate" now equated with "romantic". Love was a central topic again in the subsequent movement of [[Romanticism]], which focused on such things as absorption in nature and the [[absolute (philosophy)|absolute]], as well as [[Platonic love|platonic]] and unrequited love in German philosophy and literature.

French philosopher [[Gilles Deleuze]] linked this concept of love as a lack mainly to [[Sigmund Freud]], and Deleuze often criticized it.

{{off topic|date=August 2025}}

=== The self-expansion theory of romantic love ===
Researchers Arthur and Elaine Aron theorized that humans have a basic drive to expand their self-concepts. Further, their experience with Eastern concepts of love caused them to believe that positive emotions, cognitions, and relationships in romantic behaviors all drive the expansion of a person's self-concept.<ref>{{cite book|last1=Aron|first1=Arthur|last2=Aron|first2=Elaine N.|title=Love and the expansion of self: Understanding attraction and satisfaction|year=1986|publisher=Hemisphere|location=New York|isbn=9780891164593}}{{page needed|date=June 2021}}</ref> A study following college students for 10 weeks showed that those students who fell in love over the course of the investigation reported higher feelings of self-esteem and self-efficacy than those who did not.<ref>{{cite journal|last=Aron|first=A.|author2=Paris, M. |author3=Aron, E. N. |title=Falling in love: Prospective studies of self-concept change|journal=Journal of Personality and Social Psychology|year=1995|volume=69|issue=6|pages=1102–1112|doi=10.1037/0022-3514.69.6.1102}}</ref>

=== Relationship maintenance ===
Daniel Canary from the International Encyclopedia of Marriage<ref>{{cite journal |last1=Clover |first1=David |title= International Encyclopedia of Marriage and Family (2nd edition)|journal=Reference Reviews |date=June 2003 |volume=17 |issue=6 |pages=28–29 |doi=10.1108/09504120310490570 }}</ref> describes relationship maintenance as "At the most basic level, relational maintenance refers to a variety of behaviors used by partners in an effort to stay together." Maintaining stability and quality in a relationship is the key to success in a romantic relationship. He says that: "simply staying together is not sufficient; instead, the quality of the relationship is important. For researchers, this means examining behaviors that are linked to relational satisfaction and other indicators of quality." Canary suggests using the work of John Gottman, an American physiologist best known for his research on marital stability for over four decades, serves as a guide for predicting outcomes in relationships because "Gottman emphasizes behaviors that determine whether or not a couple gets divorced".<ref>{{Cite book|date=1 November 1993|title=What Predicts Divorce?|doi=10.4324/9781315806808|isbn=978-1-315-80680-8|last1=Gottman|first1=John Mordechai}}{{page needed|date=June 2021}}</ref>

Furthermore, Canary also uses the source from Stafford and Canary,<ref>{{Cite book|date=1 June 2001|editor-last=Harvey|editor-first=John H.|editor2-last=Wenzel|editor2-first=Amy|title=Close Romantic Relationships|doi=10.4324/9781410600462|isbn=978-1-4106-0046-2}}{{page needed|date=June 2021}}</ref> a journal on Communication Monographs, because they created five great strategies based on maintaining quality in a relationship, the article's strategies are to provide:
* ''Positivity'': being joyful and optimistic, not criticizing each other.
* ''Assurances'': proving one's commitment and love.
* ''Openness'': to be honest with one another according to what they want in the relationship.
* ''Social networks'': efforts into involving friends and family in their activities.
* ''Sharing tasks'': complementing each other's needs based on daily work.
