Morphology
ctenoid = cten + oid
The combining form 'cten-' (meaning 'comb') is not a standalone English word and is unfamiliar to most learners, so the meaning cannot be reliably derived even though the suffix '-oid' means 'like'.
Etymology
The word ctenoid comes from an old Greek root kten- meaning 'comb'. It describes fish scales with tiny comb-like 'teeth' on their edges, so the word helps you remember that these scales feel rough and look like a small comb.
