◉Etymology

From Middle English sive, syfe, from Old English sife, sibi (“sieve”), from Proto-Germanic *sibi (“sieve”), from Proto-Indo-European *seyp-, *seyb- (“to pour, sieve, strain, run, drip”). Akin to German Sieb, Dutch zeef, Proto-Slavic *sito (Russian си́то (síto), сев (sev), се́ять (séjatʹ)).

◉Usage notes
