Morphology

mosquito + fern

The compound is a straightforward noun+noun formation where the first noun specifies the type of the second, so a learner who knows 'mosquito' and 'fern' can infer it denotes a kind of fern associated with mosquitoes (e.g., very small or found in similar watery habitats). This follows regular, cross-linguistic compounding patterns and does not involve an idiomatic or metaphorical shift, so the meaning is readily derivable from the constituents.

Etymology

Mosquito fern gets its name because people noticed this tiny, floating fern in the same calm water where mosquitoes lay their eggs; the plant often forms a green cover on the water and so became linked with mosquitoes. That's why the name now means 'a small floating water fern'.
