Morphology
dicotyledonous = dicotyledon (semi-transparent) = di + cotyledon + ous
The adjective is formed by adding the productive adjectival suffix '-ous' to the noun 'dicotyledon', a standard and regular derivation.
Etymology
The word dicotyledonous comes from di- meaning 'two' and cotyledon meaning 'seed leaf', so it describes plants whose seeds have two little leaves inside them.
