Morphology

heterocycle = cycle (semi-transparent) = hetero + cycle

The combining form 'hetero-' is common in scientific vocabulary but is not a standalone everyday word for many learners, so the overall term may be only partially transparent to B1 learners.

Etymology

The word heterocycle comes from Greek parts hetero- meaning 'different' and cycle meaning 'circle' or 'ring', the same cycle in bicycle. In chemistry a heterocycle is a ring-shaped molecule where at least two of the atoms are different elements, like carbon and nitrogen, so the name means a 'different ring'.
