'anchoretish' originates from English, specifically from the word 'anchoret' (meaning 'hermit' or 'religious recluse'), with the suffix '-ish' meaning 'having the qualities of'.

'anchoret' comes from Late Latin 'anchoreta', from Greek 'anachōrētēs', meaning 'one who has retired from the world'. The adjective form 'anchoretish' was formed in English by adding '-ish'.

Initially, it meant 'having the qualities of an anchoret (hermit)', and this meaning has remained consistent in modern usage.
