Morphology

caustic = caust + ic

The adjective is formed with the Greek combining form 'caust-' + '-ic'; because 'caust-' is not a standalone English word, average learners will not reliably infer 'able to burn' from the morphemes.

Etymology

Caustic comes from the Greek root kaustos meaning 'burning'. We call a substance caustic when it can 'burn' or eat away organic tissue, which shows how the original meaning connects to the modern use.
