Etymologically, the entry records: Inherited from Middle English siker, sikker, sykkere, secre, seccre, from Old English sēocra (“sicker”), equivalent to sick + -er. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is sicker, spelled S-I-C-K-E-R, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
