Morphology

allomorph = morph (semi-transparent) = allo + morph

Formally 'allo-' = 'other' + 'morph' = 'form', so the components yield 'other form', but both elements are bound technical combining forms unfamiliar to general B1 learners.

Etymology

Allomorph comes from the Greek parts allo- 'other' and -morph 'form'. So an allomorph is literally an 'other form', which helps you remember that the same chemical compound can appear in different crystal shapes, like calcite and aragonite.
