Morphology

dicotyledon = cotyledon (transparent) = di + cotyledon

Formed by the productive combining prefix 'di-' meaning 'two' plus 'cotyledon', so the meaning 'having two cotyledons' is directly derivable.

Etymology

Dicotyledon comes from Greek parts di- 'two' and cotyledon 'seed leaf'. So a dicotyledon is a flowering plant whose seed makes two little leaves, which is why its seed often splits into two halves.
