sick¹

  • /ˈsɪk/

Sounds like sic, Sikh · Rhymes with -ɪk

Where it comes from

From Middle English sik, sike, seek, seke, seok, from Old English sēoc (“sick, ill”), from Proto-West Germanic *seuk, from Proto-Germanic *seukaz, from Proto-Indo-European *sewg- (“to be troubled or grieved”).

See also West Frisian siik, Dutch ziek, German siech, Norwegian Bokmål syk, Norwegian Nynorsk and Swedish sjuk, Danish syg; also Middle Irish socht (“silence, depression”), Old Armenian հիւծանիմ (hiwcanim, “to be weakening”).

The "very good, excellent" sense is an ameliorative semantic shift from the original sense of "in poor health". Compare similar semantic development in terrific and wicked.
