Etymology
Etymology Information

'wait-free' originates from English, specifically the words 'wait' and 'free', where 'wait' meant 'to remain in expectation' and 'free' meant 'not subject to or constrained by'.

Historical Evolution

'wait' derives from Middle English 'waiten' (from Old North French/Frankish roots) and 'free' from Old English 'frēo'; the compound 'wait-free' was coined in 20th-century computer science literature to mean 'free from waiting'.

Meaning Changes

Initially it meant simply 'not having to wait', but in concurrency theory it evolved into the precise technical meaning that each operation completes in a bounded number of steps regardless of other threads.
