Etymonline

Word Origin & History

since

mid-15c., synnes, from sithenes "since," from sithen (plus adverbial genitive -es), from O.E. siððan "then, later, after that," originally sið ðan "after that," from sið "after" + ðan, weakened form of ðam, dative of ðæt (see that). Modern

spelling replaced syns, synnes 16c. to indicate voiceless final -s- sound. O.E. sið is from PIE *se- "long, late" (cf. Ger. seit "since," Goth. seiþus "late," Skt. sayam "in the evening," L. serus "late").
