Simplified etymology

Sick is an Old English word and was the ordinary English term for someone physically unwell before ill entered the language in the early Middle Ages. It remains the usual term in American English.

Etymology

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 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.
