Middle English (as a verb): probably a back-formation from sighte, past tense of siche, sike, from Old English sīcan .
wiktionary
From Middle English sighen, syghen, syȝȝen, (also syken, sychen, syghten, etc.), from Old English sīcan(“to sigh, moan, groan”), from Proto-West Germanic *sīkan, perhaps ultimately from Proto-Indo-European *seykʷ-(“to pour out”). The Middle English infinitive forms in ȝ/gh are backformations of the past tense forms sighte, siȝhte, isiȝt, etc. Doublet of sike.
