Etymology From Middle English slitten, from Old English slītan, from Proto-Germanic *slītaną (“to tear apart”), from Proto-Indo-European *(s)leyd- (“to tear, rend (cut apart), split apart”). Possibly cognate with Latin laed- (“to strike, hurt, injure”). Doublet of slite; also related to slice through French borrowing. Apparently unrelated to English slot, whose etymology, however, is uncertain.
