Simplified etymology
Jazz appeared in the early 20th century, perhaps first meaning “liveliness, energy, or spirit”; it was used of an unusual baseball pitch in 1912 and first recorded in a musical sense in Chicago in 1915. Its origin remains uncertain and may be African, or it may be related to slang jasm, “energy” or “pep,” derived from jism, a word of unknown origin that later also meant “semen.”
