Morphology

Pulex + irritans

The first element 'Pulex' is given as a genus of fleas, so a learner who knows that constituent can infer this is a flea name; however 'irritans' is not a recognizable English word here and the Latin binomial system (genus + species) is not a productive compositional pattern for B1 learners to derive the specific meaning 'human flea'. Because part of the meaning (that it is a flea) is transparent but the precise species sense and the Latin species epithet are not predictable, this is best classified as semi-transparent.

Etymology

Pulex irritans comes from two Latin words: pulex ('flea') and irritans ('irritating'). That's why the name paints the picture of a small biting insect that bothers people, and today it refers to the common 'human flea'.
