Such words have adjectives in ‑morphic or ‑morphous, frequently both: allomorphic, enantiomorphic, isomorphous, pseudomorphous. A few adjectives in these endings do not have corresponding nouns in ‑morph, of which one is zygomorphic (Greek zugon, yoke), of a flower that has only one plane of symmetry, as in a pea or snapdragon.

A few nouns exist in ‑morphosis referring to a change of state: anamorphosis (Greek ana, back), a distorted projection or drawing which appears normal when viewed from a particular point or with a suitable mirror or lens; metamorphosis, a change of the form or nature of a thing or person into a completely different one.
