Morphology

fibrinoid = fibrin (semi-transparent) = fibrin + oid

Derived from 'fibrin' + '-oid' (resembling); the noun sense is a regular nominal use of the adjectival formation but remains technical and may not be guessable by average learners.

Etymology

Fibrinoid names a substance in tissue that looks like fibrin, the thread-like part of a blood clot, and the ending -oid means 'like' or 'resembling'. So, a fibrinoid deposit is simply material that appears 'like' fibrin.
