Yo is an English slang interjection, commonly associated with American English. It was popularized by Italian and African Americans in Philadelphia in the 1970s. It is used to signify informality, close cultural understanding, and communal bonding. It remains very popular among Philadelphia Italian Americans, possibly arising from the Italian language word ‘io’ (meaning ‘I’). In Italian, first person statements are often preceded by io.
Although often used as a greeting, yo may come at the end of a sentence, often to direct focus onto a particular individual or group or to gain the attention of another individual or group. It may specify that a certain statement that was previously uttered is more important, or may just be an ‘attention grabber’ (e.g. ‘Listen up, yo!’). In the Japanese language, the sentence-final particle ‘yo’ is used to emphasize sentences as is often the case in English slang as above, but is etymologically unrelated. ‘YŌ’ is also used by Japanese teens as casual greetings between friends, but is pronounced with a more drawn-out tone.
