English words of Greek origin "bacterium" < βακτήριον 'stick (diminutive)' is a kind of microorganism rather than a small stick or staff. This also applies to combining forms used in neologisms: "-cyte" or "cyto-" < κύτος 'container' means biological cells, not arbitrary containers; "-oma" < -ωμα, a generic morpheme forming deverbal nouns such as "diploma" 'a folded thing' and "glaucoma" 'greyness', comes to have the very narrow meaning of 'tumor' or 'swelling', on the model of words like "carcinoma" < καρκίνωμα. For example, "melanoma" does not come from Greek μελάνωμα 'blackness', but rather from the modern combining forms "melano-" 'dark (in biology)' + "-oma" 'tumor'.
