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’.
