Morphology

cotton + grass

The noun-noun composition 'cotton grass' is directly interpretable as a grass-like plant that has cotton-like (fluffy) fibers, so a learner who knows 'cotton' and 'grass' can infer the basic meaning. This follows a common cross-linguistic compounding pattern for describing plants and therefore is immediately comprehensible at B1 even if the precise botanical details are unknown.

Etymology

Cotton grass gets its name from how the plant looks: the tops have soft, white tufts that look like bits of cotton on a low grass-like plant in bogs. So the name now means the 'bog plant' with cotton-like tufts.
