the.com/changer

means Someone who made a single alteration or became different, now permanently filed under that one act as if it were their whole identity.

from Straightforward stuff: 'change' traces back through Old French 'changier' to Late Latin 'cambiare' (to exchange or barter), itself from a Gaulish/Celtic root meaning 'to bend or turn.' Add the agent suffix '-er,' bolted onto countless English verbs to mean 'one who does the thing,' and you get 'changer' — literally, the one who turns it. The word's been doing this job since Middle English, no twist required; the irony here is entirely the entry's, not the etymology's.
