Etymology

It is inherited from Middle English synnes, syns,[3][4] a contraction of sithenes, formed from sithen (“after that, since”) with the adverbial genitive ending -es;[4][5][6] sithen is in turn inherited from Old English siþþan (“afterward, later; as soon as”), from the phrase sīþ þan (“after that”),[4][7] made up of sīþ (“after”) (see sith) and þan, a weakened form of þām, the dative of þæt (“that”).[4][8] Sīþ is related to German seit (“since”) and Gothic 𐍃𐌴𐌹𐌸𐌿𐍃 (seiþus, “late”), and outside Germanic to Latin sērus (“late”).[7][6][9] The Oxford dictionaries also allow derivation from the dialect form sin, a shortening of sithen.[10][11][12] German seitdem is formed in the same way.[7][13]

Earliest recorded meaning

Afterwards; from then until now (as an adverb, before 1425 in a version of Piers Plowman, and Old English siþþan about 725, in Beowulf).[7]

Semantic evolution

As a conjunction, “from the time when”, since is recorded from the late 14th century,[4][3] and in the causal sense “because, inasmuch as” from about 1450, a development like that of French puisque.[3][14] The preposition dates from the early 16th century (1515 in Barnhart).[3][4][15] The sense “before now, ago”, with a word such as long (long since), is from the late 15th century.[4][16] In the 16th century the spelling since replaced syns, synnes to show that the final sound is a voiceless s, as ice replaced is and twice replaced twies.[7][4] Shakespeare could also use it to mean “when” (thou rememb'rest since once I sat upon a promontory), a sense now obsolete.[8] Since when?, often expressing disbelief, is attested from 1907.[4]
