• vt. 影響；感染；感動；假裝
• vi. 傾向；喜歡
• n. 情感；引起感情的因素

前綴af-同ad-, 去，往。詞根fect, 同fact, 做。該詞根衍生出兩個截然相反的意思：1. 做出來的樣子，假裝。2. 真心實意的做，打動，影響。

affect

affect: There are two distinct verbs affect in English: ‘simulate insincerely’ [15] and ‘have an effect on’ [17]; but both come ultimately from the same source, Latin afficere. Of compound origin, from the prefix ad- ‘to’ and facere ‘do’, this had a wide range of meanings. One set, in reflexive use, was ‘apply oneself to something’, and a new verb, affectāre, was formed from its past participle affectus, meaning ‘aspire or pretend to have’.

Either directly or via French affecter, this was borrowed into English, and is now most commonly encountered in the past participle adjective affected and the derived noun affectation. Another meaning of afficere was ‘influence’, and this first entered English in the 13th century by way of its derived noun affectiō, meaning ‘a particular, usually unfavourable disposition’ – hence affection.

The verb itself was a much later borrowing, again either through French or directly from the Latin past participle affectus.
