英文詞源


compound
compound: There are two distinct words compound in English. The one meaning ‘combine’ [14] comes ultimately from Latin compōnere ‘put together’. Old French took two verbs from this: the perfect stem composproduced composer (whence English compose) while the infinitive became compondre, source of English compound. Its original Middle English form was compoune; the final d came from the adjectival use of the past participle compouned. Compound ‘enclosure’ [17] is of Eastern origin: it comes from Malay kampong ‘group of buildings, village’, and was borrowed via Portuguese campon or Dutch campoeng.

The English form was no doubt remodelled on the basis of compound ‘combine’.

=> compose, composite, position
compound (v.)
"to put together," late 14c., compounen "to mix, combine," from Old French compondre, componre "arrange, direct," from Latin componere "to put together" (see composite). The -d appeared 1500s in English on model of expound, etc. Related: Compounded; compounding.
compound (n.2)
"a compound thing," mid-15c., from compound (adj.).
compound (n.1)

compound (adj.)
