IPA: /ɪɡˈzɔːstʃən/
KK: /ɪɡˈzɔːstʃən/
A state of extreme tiredness or fatigue, often resulting from hard work or physical activity.
After working all day, I felt a deep sense of exhaustion.
Exhaustion → It is formed from "ex-" (meaning out) and "haustus" (from "haurire", meaning to draw or to drink). The word describes the state of being completely drawn out or drained of energy.
Think of being 'drawn out' ('haustus') until you have nothing left — that's what exhaustion means.
