Appears in

From Middle English sperme, through Latin sperma, from Greek sperma ('seed'), related to speirein ('to sow or scatter'). The reproductive sense continues the ancient seed metaphor. The historical oil-and-wax sense comes through sperm whale, whose spermaceti was once mistaken for the animal's seminal fluid.
