Morphology
even-pinnate + leaf
The phrase is compositionally built: 'even-pinnate' (even + pinnate) describes the leaflet arrangement and combining it with 'leaf' yields a leaf with paired leaflets and no terminal leaflet. A learner who knows the constituents ('even' and 'pinnate') can directly infer this descriptive, literal meaning, so the expression is transparently derived from its parts.
Etymology
Even-pinnate leaf names a leaf made of many small leaves (leaflets) that sit in pairs along a central stem and that ends with a matching pair instead of a single leaflet. The word even points to that final matching pair and pinnate shows the leaf has leaflets on a central stalk, so the name means 'ending with a pair of leaflets'.
