the.com/sickness
the body's loud, unglamorous strategy for forcing a stubborn animal to finally rest
means the state of being ill or unwell in body or mind, often marked by nausea, weakness, or the urge to vomit
from From Old English seocnes, built on seoc 'ill, sick' plus the noun-making ending -nes that turns a quality into a thing. The root seoc is shared across the old Germanic languages — a cousin of German siech and Dutch ziek — though where it ultimately came from before that is uncertain. The 'feeling like you might vomit' sense ('seasickness,' 'morning sickness') is a later narrowing, and the older, broader meaning of plain 'illness' is the one that built the word.
