meristic positive

Morphology

meristic = merism (opaque) = mer + istic

The combining form 'mer-' (meaning 'part') is not a standalone English word and the adjective is technical and unlikely to be predictable for average learners.

Etymology

Meristic comes from the Greek root meros, meaning 'part'. It is used in biology for counting separate body 'parts' — for example fin rays or scales — so meristic data are simply counts of parts that help scientists tell different kinds of fish apart.
