IPA: /ɪˈmɑːrdʒɪneɪt/
KK: /ɪˈmɑr.dʒɪ.neɪt/
Describing something that has a small indentation or notch at its edge, often seen in the tips of leaves or petals.
The emarginate leaves of the plant give it a unique appearance.
Emarginate is formed from "e-" (meaning out) and "marginate" (from Latin "margo", meaning edge or border). The word describes something that has a notch or indentation at the edge, effectively meaning to have an edge that is cut out or notched.
Think of something that has an 'edge' ('margo') that is 'cut out' ('e-') — that's what emarginate means.
