Morphology

abruptly-pinnate + leaf

The phrase is compositionally built from 'pinnate' (a feather-like arrangement of leaflets) and 'leaf', so a learner who knows those parts could grasp it refers to a type of pinnate leaf. However, the prefix 'abruptly-' encodes a specific technical morphological detail (how the leaf terminates with a pair of leaflets rather than a single terminal leaflet) that is specialized botanical vocabulary and not fully predictable from general knowledge, so it is only partially transparent to a B1 learner.

Etymology

Abruptly-pinnate leaf gives a clear picture: a feather-like pinnate leaf that stops suddenly and ends with a 'pair' of small leaflets instead of a single 'tip'. So the name helps you remember it means a leaf that finishes 'abruptly' at the end with two leaflets, not one.
