Morphology

dermoid = derm (semi-transparent) = derm + oid

The suffix '-oid' ('resembling') is productive, but 'derm' is a combining form (not a common standalone word), so the meaning is clear to those familiar with medical/Greek forms but not to average learners.

Etymology

Dermoid comes from the Greek root derm ('skin') plus the ending -oid ('like'), so the word simply means 'skin-like'. That is why a dermoid as a noun names a kind of birth cyst that can contain skin, hair, or even teeth.
