Morphology

Ricinus + communis

This is a Linnaean binomial: 'Ricinus' names the plant genus and 'communis' (Latin for 'common') signals the common species, so a learner who knows both elements could infer it refers to the common species of the Ricinus plant (i.e., a plant). However, the detailed sense — that it is the castor oil plant, a tall tropical shrub with seeds producing castor oil and the toxin ricin — is not derivable from the parts, and the species epithet is Latin rather than a familiar English word, so the transparency is only partial.

Etymology

Ricinus communis comes from Latin names. The word Ricinus meant a 'tick' because each shiny seed looks like a small tick, and communis means 'common', so the name describes the 'common tick' plant, the castor oil plant known for its seeds.
