Thrift was formerly a word for profits, now it makes sense. But I recognize the snowclone as a popular 16th century way to form personal verb-noun descriptors like cutpurse, upstart, sawbones, spoilsport, dreadnought. This is still productive because midwit is a recent addition. (Eh, I suppose mid isn't a verb, but I think it's the same pattern.)

Huh! Spanish and Portuguese still use this pattern (verb+noun → noun), like Spanish matafuego 'fire extinguisher' (literally 'killfire'), Spanish rascacielos (literally 'scrapeskies'), Portguese arranha-ceu (literally 'scrape-sky').

(Spanish does this more than Portuguese, but also Wiktionary has been more thorough in categorizing the Spanish examples compared to the Portuguese examples.)

It's cool to be reminded that this pattern also has a history in English.

Another example I was thinking of, pasatiempo/passatempo, actually has an exact English equivalent, pastime.

the etymology of snowclone itself is amusing ;)
