Origin & History of “mass”

English has two distinct words mass. The one meaning ‘Eucharist’ (OE) comes from late Latin missa, a noun use of the feminine past participle of mittere ‘send’ (source of English admit, commit, dismiss, mission, etc) possibly arising from Ite, missa est ‘Go, it is the dismissal’, the last words of the Latin eucharist service.

Mass ‘amount of matter’ (14th c.) comes via Old French masse and Latin massa from Greek maza ‘barley cake’, hence ‘lump, mass’. The derivative massive (15th c.) goes back ultimately to vulgar Latin *massīceus. A possible relative is massage (19th c.), a borrowing from French. It was a derivative of masser ‘massage’, which may have been acquired from Portuguese amassar ‘knead’, a verb based on massa ‘mass, dough’.
