Morphology

false + oat

The noun meaning 'a grass resembling oat' is directly derivable from combining 'false' (not genuine; imitation) with 'oat' (the cereal), since English 'false X' routinely labels things that look like but are not the genuine X. This adjective+noun compositional pattern is cross-linguistically common and would be readily guessed by a B1 learner who knows both constituents.

Etymology

False oat gets its name because the grass looks like real oat: its long top parts with seeds look like oats, but it is false — 'not a true oat'. So the name helps you remember it is a grass that looks like oat but is different.
