Morphology

cotton + thistle

The compound is a straightforward noun–noun composition: 'cotton' (fluffy fibers) + 'thistle' (a spiny plant) yields a subtype of thistle characterized by cotton-like hairs. This descriptive, compositional pattern is transparent and predictable, so a B1 learner who knows both constituents can infer the meaning.

Etymology

The noun cotton thistle comes from how the plant looks: it is a thistle covered in soft white hairs that look like cotton. That's why the name means 'a tall, white, hairy thistle'.
