allomerism singular

Morphology

allomerism = allomer (opaque) = allo + mer + ism

The components are specialized combining forms used in chemistry (allo- + -mer) and the meaning is technical and not inferable by an average learner.

Etymology

The word allomerism comes from Greek parts allo- 'other' and -mer 'part', the same mer you see in polymer. So allomerism names a case where substances have 'other parts' (different make-up) but still share the same crystal form.
