Photographer Unknown, (Pilus)

The pil-based words for “hair”, are all derived from the Latin word “pilus” (“hair”). A fairly common adjective, pilose, means “covered with fine soft hair.” Deceptively similar-looking is the word ‘pilous’, which is a more hardcore-science adjective defined as “characterized by or abounding in hair, hairy”. An example of the use of that word is the following sentence: ‘He is covered with a rough pilous epidermis’.
