Morphology

acinar = acinus (opaque) = acin + ar

Formed from the technical anatomical noun 'acinus' plus the adjectival suffix '-ar'; the root 'acin-' is a rare, specialized combining form not familiar to average B1 learners.

Etymology

The word acinar comes from the Latin acinus, meaning 'berry' or 'small sac', so imagine tiny berry-like pouches inside a gland. That's why acinar describes parts of glands that look like little sacs.
