Morphology

Phthirius + pubis

The compound is compositionally transparent: given 'Phthirius' (a genus of human‑infesting insects) and 'pubis' (the front pelvic region), a learner can infer it denotes an insect associated with the pubic area. Although technical/Latinized, the meaning follows a straightforward biological naming pattern that a B1 learner who knows both constituents can deduce.

Etymology

Phthirius pubis is a scientific name that comes from old words for a small 'louse' phthir- and the 'pubic' area pubis. It literally means 'louse of the pubic hair', so the name fits the tiny insects that live in coarse pubic hair and make the skin itch.
