'clarity-enhancing' originates from combining the noun 'clarity' and the present participle 'enhancing'. 'clarity' ultimately comes from Latin 'claritas' meaning 'clearness, brightness', and 'enhance' comes from Old French 'enhauncer' (via Vulgar Latin) meaning 'to raise or increase'.

'clarity' passed into Middle English via Old French 'clarite' from Latin 'claritas', while 'enhance' developed from Old French 'enhauncer' and Middle English 'enhauncen'; the adjectival '-ing' form 'enhancing' was later attached to nouns to form compounds such as 'clarity-enhancing'.

Initially, 'clarity' often referred to physical brightness or clearness and 'enhance' to raising or improving value; when combined as a compound adjective it evolved to the specific sense 'serving to make something clearer' (improving intelligibility or precision).
