Morphology
emargination = emarginate (semi-transparent) = margin + ation
Formally built from the verb 'emarginate' + suffix '-ation' and ultimately related to 'margin', but the initial 'em-' form and the specialized biological sense make it less obvious to average learners.
Etymology
Emargination comes from Latin parts e- meaning 'out' and margin meaning 'edge', and it shares the same root as the common English word margin. So an emargination is a small notch or indentation cut into the edge of a leaf, wing, or shell.
