O.E. coc, from V.L. cocus "cook," from L. coquus, from coquere "to cook, prepare food, ripen, digest, turn over in the mind" from PIE root *pekw- "to cook" (cf. Oscan popina"kitchen," Skt. pakvah "cooked," Gk. peptein, Lith. kepti "to bake, roast," O.C.S. pecenu "roasted," Welsh poeth "cooked, baked, hot"). Germanic languages had no one native term for all types of cooking, and borrowed the Latin word (cf. O.S. kok, O.H.G. choh, Ger. Koch, Swed. kock).14世紀以後才作為動詞用，指廚師烹飪的這一系列行為.cook（v.）late 14c., from cook (n.); the figurative sense of "to manipulate, falsify, doctor" is from 1630s. Related: Cooked, cooking. To cook with gas is 1930s jive talk. 而cooker這個詞=cook (v.) + -er (施動的人或事物).1884年才出現的。也就是說，之前我們已經有了廚子這個概念，炊具的概念是後來出現的而bake出現的時候是一個動詞O.E. bacan "to bake," from P.Gmc. *bakanan (cf. O.N. baka, M.Du. backen, O.H.G. bahhan, Ger. backen), from P.Gmc. *bakan "to bake," from PIE *bheg- "to warm, roast, bake" (cf. Gk. phogein "to roast"), from root *bhe- "to warm" (see bath). Related: Baked (M.E. had baken); baking. The noun meaning "social gathering at which baked food is served" is attested by 1846, Amer.Eng. Baked beans attested by 1803. baker的意思是這樣的。O.E. bæcere "baker," agent noun from bacan "to bake" (see bake). 又比如drive這個單詞，最初出現的時候也是動詞形式。加er就變成司機。猜測：如果一個單詞起源時候是動詞，那麼加er構成人，即agent noun from。如果本身起源的時候是名詞，則不一定。當然大部分應該還是的，比如villager，lawer（該結論需要進一步驗證，歡迎補充一些以er結尾但非agent noun from的單詞）PS:其實cooker也可以是廚子的Definition of COOKER: one that cooks: asa : a utensil, device, or apparatus for cookingb : a person who tends a cooking process : cookc British : stove
因為cook這個詞最初出現的時候就是一個名詞，本身就有廚師的意思
