Morphology

acanthous = acanthus (opaque) = acanth + ous

The combining form 'acanth-' (or the noun 'acanthus') is obscure to typical learners, so adding '-ous' does not make the meaning transparently obvious.

Etymology

Acanthous comes from the old Greek word akantha, which means 'thorn' or 'spine'. So something acanthous is 'thorn-like' or 'spiny', like the stems of a cactus or the tiny protective spikes on some sea creatures.
