Morphology

American + mastodont

The meaning 'a mastodont from America' is directly and compositionally derived from 'American' (of the Americas) + 'mastodont' (an extinct mammal). This follows a simple adjective + noun pattern common across languages, so a B1 learner who knows both constituents can infer the MWE's meaning.

Etymology

American mastodont gets its name from old words for 'breast' and 'tooth' because its back teeth are large and rounded, like a thick bump. So American mastodont refers to the big, elephant-like animal that lived in North America and is now 'extinct'.
