'uneven-textured' originates from English, composed of the adjective 'uneven' (from Old English elements where 'un-' meant 'not' and 'even' from Old English 'efen' meant 'level') and 'textured' (derived from Latin 'textura' via Old French/Middle English), where 'textura' meant 'a weaving' or 'the way something is woven or constructed'.

'uneven' developed from Old English components ('un-' + 'efen') meaning 'not level', while 'texture' comes from Latin 'textura' (from 'texere', to weave) and passed into Middle English as 'texture' or 'textured'; the compound adjective 'uneven-textured' is a modern English formation combining these elements to describe surface quality.

Initially, the elements meant 'not level' (uneven) and 'weaving/structure' (texture); over time the combined phrase came to mean 'having an irregular surface or feel' in modern usage.
