'non-Turkic' is a modern English compound formed from the prefix 'non-' (from Latin 'non' meaning 'not') attached to 'Turkic' (formed from 'Turk' + suffix '-ic').

'Turkic' ultimately derives from the ethnonym 'Turk' (Medieval Latin 'Turcus'), itself from Old Turkic forms such as 'Türük/Türk'; the English adjectival suffix '-ic' was added to form 'Turkic'. The negative prefix 'non-' has been used in English since Middle English (from Latin 'non') to create compounds like 'non-Turkic'.

The compound originally and consistently meant 'not Turkic' (i.e., not of Turkic origin or character) and has retained that basic meaning.
