Morphology

tricyclic + antidepressant + drug

The phrase is fully compositional: 'tricyclic' modifies 'antidepressant' and 'drug', so a B1 learner who knows the constituent meanings can infer it refers to a type/class of medication used to treat depression (specifically the tricyclic class). The structure (adjective + noun + noun) and the logical stacking of category words make the overall meaning predictable and transparent.

Etymology

Tricyclic antidepressant drug gets its name from the medicine's shape: tri- means three and cyclic means ring, so the medicine is built from 'three rings'. They help certain 'mood chemicals' stay longer in the brain to lift mood and treat depression, so the name points to this group of older antidepressant medicines.
