Etymology
This word results from the merging of two stems: (a) Proto-Baltic *spriesti < *spried-ti < Proto-Indo-European *spreyd- (“to press, to squeeze, to block”) (cf. Sudovian cognate saspriziz (“squeeze, crush”)); and (b) Proto-Baltic *sprensti, from *sprend-ti, from Proto-Indo-European *sprend- (“to pull, to stretch, to jump”), from *per-, *sper- (“to pull, to kick, to scatter, to strew, to sputter”) (whence also Latvian spert and sprēgāt, q.v.). The meaning of the (b) forms, perhaps with some influence from the (a) forms, has become dominant, evolving from probably “to pull, to stretch, to drag”, via uses such as sprīdi spriest “to stretch a span”, i.e., “to measure (a span, a gap) by stretching one's fingers”, to “measure” > “evaluate” > “judge”. The (a) form meaning has basically disappeared in standard Latvian, but it can still be found in several dialects, where spriest can still mean “press, squeeze”, and in the standard language in some derived terms (e.g., spriesties, iespriest, saspriest). Cognates of the (b) forms include Lithuanian sprę́sti (“to drive, stick into, to squeeze through, to throw, to stretch; to tighten, to harness; to judge, to decide, to solve”), Old Church Slavonic прѧсти (pręsti, “to spin (yarn)”), Russian прясть (prjastʹ), Ukrainian пря́сти (prjásty), Bulgarian преда́ (predá, “I spin”), Czech přísti, Polish prząść.
