It may also be used to express excitement, surprise, disbelief, enthusiasm, anger, or amazement.

Etymology and history

The interjection yo was first used in Middle English.<ref>Template:Cite web</ref><ref name="Online Etymology Dictionary yo (interjection) etymological definition">Template:Cite web</ref> In addition to yo, it was also sometimes written io.<ref>Yo, Merriam-Webster's Collegiate Dictionary</ref>

Though the term may have been in use in an isolated manner in different contexts earlier in English, its current usage and popularity derives from its use in Philadelphia's Italian American population in the twentieth century, which spread to other ethnic groups in the city, notably among Philadelphia African Americans, and later spread beyond Philadelphia.<ref>Template:Cite book</ref>

From the late twentieth century, it frequently appeared in hip hop music and became associated with African American Vernacular English.
