"Pinnate" derives from the Latin word pinna, meaning "feather". One common term of these leaves is "feather compound". Total number of trees in this group is quite large. So, to keep group smaller, we can further subdivide this group into
a) With a terminal leaf (botanists call them imparipinnate), listed this page
b) Without terminal leaf (paripinnate) listed in a separate page.
One easy way to remember these two terms is "pari" is from pair. Paripinnate leaf always has leaflets in pair, that is, even number of leaflets. The opposite, imparipinnate leaf will have odd number of leaflets (since it has a terminal leaflet).
Note that Neem leaflets are incidentally toothed. Most leaflets of the trees in this group are not toothed.
