since 自从，后来，因为
来自中古英语 sinnes,缩写自 sithence,来自 sithen,在此以后，-es,-ce,副词后缀，来自古英语 siththan,合成自短语 sith thaem,在此以后，来自 sith,自从，之后，thaem,那，与格形式于 that. 参照 sith,自从，之后。
- since
- since: [15] Since is a contracted form of Middle English sithenes ‘since’. This in turn went back (with the addition of a final -s) to Old English siththan, a compound adverb and conjunction formed from sīth ‘after’ (a relative of German seit ‘since’) and thām ‘that’.
- since (adv.)
- early 15c., synnes, from sithenes "since," from sithen (plus adverbial genitive -es), from Old English siððan "afterward, from now on, hereafter, further, later, as soon as, after that," originally sið ðan "after that," from sið "after" (see sith) + ðan, weakened form of ðam, dative of ðæt (see that).
As a conjunction from late 14c.; as a preposition from 1510s; "from the time when," hence "as a consequence of the fact that." Modern spelling replaced syns, synnes 16c. to indicate voiceless final -s- sound. Since when? often expressing incredulity, is from 1907.
