Morphology

ambrosia + trifida

This is a botanical binomial: the genus name 'Ambrosia' (ragweed) plus the species epithet 'trifida' (from Latin meaning 'three‑cleft' or 'three‑lobed'), so the phrase literally denotes a specific Ambrosia species characterized by three‑lobed leaves. Because the name is directly descriptive and follows the regular genus+descriptor pattern found across languages, a learner who knows both constituents can infer it denotes a type of ragweed.

Etymology

Ambrosia trifida joins Ambrosia, a word that means 'food of the gods', and trifida, which means 'split into three'. The second part describes the plant's three-lobed leaves, so the name helps you remember this tall 'giant ragweed'.
