Morphology

crabgrass = crab + grass (semi-transparent) = crab + grass

Formally a compound of 'crab' + 'grass' so the components are visible, but the naming is metaphorical (referring to the plant's crab-like creeping habit) so the exact meaning 'weed with creeping stems' is not fully predictable from the parts.

Etymology

Crabgrass is simply crab + grass. Gardeners named it that because its thin stems spread out like a crab's legs and root easily, which is why it quickly takes over lawns.
