Etymology
Etymology Information

'half-asleep' originates from English, specifically the words 'half' and 'asleep', where 'half' comes from Old English 'healf' meaning 'half; one of two equal parts' and 'asleep' developed from Old English 'on slǣpe' (with 'on' later becoming the a- prefix) where 'slǣp' meant 'sleep'.

Historical Evolution

'asleep' changed from Old English 'on slǣpe' to Middle English 'aslepe' and eventually became the modern English word 'asleep'; 'half-asleep' is a compound formed by joining 'half' + 'asleep' in Late Middle to Early Modern English, producing the modern compound 'half-asleep'.

Meaning Changes

Initially, it meant 'in a state of partial sleep; half in sleep', and over time it has retained that basic sense while also being used figuratively to mean 'drowsy' or 'not fully attentive'.
