Morphology

abruptly + pinnate

The phrase is partly compositional: 'abruptly' conveys suddenness and 'pinnate' identifies the leaflet arrangement, so a learner who knows both words could infer that the pinnate form has an abrupt/quick termination rather than a tapered one. However, the precise botanical detail (that the leaflets end with a pair at the apex rather than a single terminal leaflet) is a specialized, non-obvious specification that is not fully predictable from the two constituents alone.

Etymology

Abruptly pinnate describes a leaf that is feather-like (pinnate) but 'ends suddenly' with a pair of small leaves at the tip (the abruptly part). So, it means the leaflets finish in a pair at the tip rather than as a single leaflet.
