Sense: verb/1
For verb sense 1, overwork means doing or demanding more work than is good for health. Exhaust focuses more on the result: someone has no energy left, even if work was not the only cause. Overstrain is more formal and often suggests physical or mental damage from too much effort. Wear out is common in everyday speech and is broader, because people, shoes, or machines can all wear out. Burn out usually describes a longer process of pressure that leaves someone empty and unable to care. A manager may overwork interns during a busy month; months of that pressure may burn them out.
Etymology
Overwork is a modern English compound built from over-, meaning 'too much', and work. The verb first names working beyond a healthy limit or making another person do that, and the noun later names the harmful condition that comes from it.
