A notch or cut in the edge of something, often seen in margins or outlines.
The emargination on the leaf's edge helps to identify the plant species.
Emargination is formed from "e-" (meaning out) and "margo" (meaning edge or border) combined with the suffix "-ation" (indicating a process or action). The term refers to the process of creating a notch or indentation at the edge or border of something.
Think of 'e-' meaning 'out' and 'margo' meaning 'edge' — emargination describes the action of creating an indentation or notch at the edge.
