Từ nguyên (Tiếng Anh)

As a greeting first attested in 1859, attested first as a cry of sailors and huntsmen (first attested in the 1400s; compare e.g. huzzah, giddyup). Originally from Middle English yo, io, ȝo, yeo, yaw, variant forms of ya, ye (“yes, yea”), from Old English ġēa (“yes, yea”), from Proto-Germanic *ja (“yes, thus, so”); or perhaps from Old English ēow (“Wo!, Alas!”, interjection). Compare Danish, Swedish, German, Norwegian jo (“yes (flexible meaning)”), Dutch jow (“hi, hey”) and Dutch jo (“hi, hey”). More at yea, ow, ew.
Modern popularity apparently dates from World War II (claimed to be a common response at roll calls; see definition 4), and then most intensely attested in Philadelphia, Pennsylvania; it thence spread globally from American dominance of pop culture post-WWII.
