From Old Dutch sint, with a suffix -s. The form is a nasal variant of Germanic *sīþiz, also found in Old High German sint. According to some, sint is instead shortened from sīdent, which itself is related with Old English siþþan and Old Norse síðan. This is, however, improbable because sint is already found in the oldest stages of both Dutch and German. Modern Dutch sinds is therefore, in all likelihood, just an indirect cognate of the similar sounding English since. The onset s- (instead of expected z-) is due to a prepositioned te (“to”), thus *te zinds → *tzinds → sinds. Immediately cognate with Luxembourgish zanter. Also cognate with German seit and English since.
