Morphology

lobefin = lobe + fin (transparent) = lobe + fin

Meaning is directly composed from 'lobe' + 'fin' (a fin with lobes), so learners recognizing both parts can infer the term.

Etymology

Lobefin comes from the English parts lobe (a 'rounded part', as in 'earlobe') and fin ('fin' of a fish). So a lobefin is a fish with thick, rounded fins that look like 'lobes', which helps explain why these fish are linked to the early animals that moved onto land.
