## AI Etymology
Unconformity comes from un- ('not') + conformity, from Old French conformite, from Late Latin conformitas, from Latin conformare ('to fashion, shape alike'), from com- ('together') + formare ('to form'), from forma ('shape, form'). The historical chain includes Old English un-, Latin conformare, and Latin forma. The quoted older senses, "not", "to fashion, shape alike", "together", "to form", and "shape, form", supply the semantic anchors for unconformity. The formation is best read as compound and borrowed: the word unconformity carries its older form-history into a compact English lexical shape. In present English it is used as a noun, "lack of conformity; a surface of contact between rock strata of differing age". Related English forms include conform, conformity, and nonconformity. The result is a noun whose etymology preserves both the older form and the later English specialization.
