Morphology

crazy + weed

The combination 'crazy' + 'weed' does give a clue — it suggests a weed associated with 'crazy' effects or abnormality — but the MWE refers to a specific group of leguminous plants that cause locoism in livestock, a technical meaning not directly derivable from the parts. A B1 learner could infer that it is an unusual or harmful weed, yet would not reliably infer the precise toxic/medical sense, making it only partially predictable.

Etymology

Crazy weed The plant name crazy weed comes from what the plant does to animals. When cattle eat the weed, its poison can make them act wild and unsteady, so they look 'crazy', and farmers used that picture to name the plant.
