Morphology

Canadian + fleabane

This is a straightforward adjective + noun combination: 'Canadian' (from Canada) modifies 'fleabane' (a type of weed), so the phrase simply denotes a fleabane associated with Canada. The meaning is literal and follows standard cross-linguistic adjective-noun composition, so a B1 learner who knows both constituents will understand it.

Etymology

Canadian fleabane gets its name from an old belief: people thought the plant would keep fleas away, so they called it fleabane, literally 'to ban' fleas, and added Canadian because it was common in North America. That's why the name now refers to the common roadside weed with small yellowish flowers.
