Morphology
carcinoid = carcinoma (semi-transparent) = carcin + oid
The formation 'carcinoma' + '-oid' ('resembling a carcinoma') is morphologically regular, but both elements are medical/technical (and '-oid' is not widely known), so the meaning is only partially accessible to an average learner.
Etymology
Carcinoid comes from the Greek word karkinos ('crab'), the same root as cancer, and the ending -oid ('like'), as in android. So a carcinoid is a 'cancer-like' small tumor: it looks like cancer but often grows slowly and can cause symptoms by making extra serotonin.
