köken: From Middle Dutch siec, from Old Dutch siec, from Proto-West Germanic *seuk, from Proto-Germanic *seukaz. Cognate with English sick, German siech, Swedish sjuk. Doublet of sick.
köken: Inherited from Old Catalan malate, malaute, from Latin male habitus (“ill-kept, run down”). The sound changes approximately ran as follows: *[maˈlaβtu] > [maˈlau̯te] > [maˈlaɫt]. The last stage involves a reidentification of coda [u̯] as the phoneme /l/, heavily velarized in coda positions. Cf. Catalan colze < colde < *coude < *[ˈkoβ(e)do] < Latin cubitum.

Inherited from Old Galician-Portuguese enfermo, from Latin īnfirmus (“sick, feeble”), from in- + firmus (“firm”), from Proto-Indo-European *dʰer-mo-s (“holding”).
