simon

Uncertain. One theory suggests derivation from a joke based on the bible verse Acts 9:43, rendered as “Peter lodged with Simon a tanner”, a pun on the meanings of lodge (“stay in a place; put away money”). Partridge suggests that this not possible given the dates, however, and suggests instead derivation from some unknown person’s name. Attested from the late 17th century, with synonymous tanner attested from the 18th. Compare also simony, from a different biblical figure, Simon Magnus. The “US dollar” sense derives from the earlier “sixpence”, perhaps influenced by the $ symbol.
