Origin of sicker

Inherited from Middle English siker, sikker, sykkere, secre, seccre, from Old English sēocra (“sicker”), equivalent to sick + -er.

From Middle English siker, from Old English sicer, sicor, from Proto-West Germanic *sikur (“free, secure”), from Latin sēcūrus (“secure”, literally “without care”). Doublet of sure and secure.

Inherited from Middle English *sikeren (attested only as sikeriez (“(it) trickles, (it) leaks, (it) oozes”)), from Old English sicerian (“to ooze, seep”), from Proto-West Germanic *sikarōn, from Proto-Germanic *sikarōną (“to trickle”), from Proto-Germanic *sīką (“slow running water”). Cognate with German Low German sickern (“to seep”), German sickern (“to seep, trickle”). Akin also to English sitch.
