Morphology

wild + mustard

The meaning 'a mustard plant growing naturally and often as a weed' is directly and compositionally derived from 'wild' (growing naturally/untamed) + 'mustard' (a plant). This is a literal, cross-linguistically common compound, so a B1 learner who knows both words will readily infer the MWE meaning.

Etymology

The noun wild mustard simply describes a bright yellow plant that grows on its own in fields. The name joins wild (growing in the open) and mustard (a plant like the spice), so it came to mean 'a common weed' that can harm crops.
