英語の語源
stifle
stifle: [14] Stiffle was probably adapted from Old French estouffer ‘choke, smother’. This in turn went back to a Vulgar Latin *extuffāre, which may have been a blend of *extūfāre ‘take a steam bath’ (source of English stew) and late Latin stuppāre ‘stop up, plug’ (source of English stop and stuff). => stew, stop, stuff
stifle (v.)
late 14c., "to choke, suffocate, drown," of uncertain origin, possibly an alteration of Old French estouffer "to stifle, smother" (Modern French étouffer), itself of uncertain origin, perhaps from a Germanic source (compare Old High German stopfon "to plug up, stuff"). Metaphoric sense is from 1570s. Related: Stifled; stifling.
