Etymology
The origin of this word is not entirely clear. It has been compared with Ancient Greek κεντέω (kentéō, “to prick, to pierce”), from Proto-Indo-European *ḱent- (“to pierce”): its zero grade *ḱn̥t would have yielded Proto-Baltic *šint-, whence Latvian sīt-, probably the stem of archaic term sīts (“hunting spear”). This hypothesis, however, does not explain the short i in the present stem sit- (with the s in the infinitive from *sit-ti > sist). A possibly better hypothesis is to derive sist from Proto-Indo-European *sey- (“to stretch one's arm; tension, strength”): its zero grade *si- would have yielded Proto-Baltic *sit- with an extra t, whence sit-ti > sist. The meaning would have changed from “to flex one's muscles” to “to use one's muscles (to hit),” whence “to hit.”
