Morphology

hair + grass

The compound is transparently built from 'hair' (fine, hair-like) + 'grass' (a narrow-leaved plant), so its meaning—a grass with very fine, hair-like leaves—is directly derivable from the constituents. This noun-noun compounding pattern is morphologically straightforward and cross-linguistically common, so a B1 learner who knows both words should be able to infer the referent even if the term is somewhat specialized.

Etymology

Hair grass comes from its very thin, hair-like leaves that look like soft hair and form a low grass carpet in a fish tank. That's why the name helps you remember it is a small water plant that covers the bottom, adds oxygen to the water, and gives shelter to small fish.
