Etymology: Albinism is, on the surface, a plain compound: "albino" with the suffix "-ism" attached. The more interesting part is the first half. "Albino" is itself a borrowing from Portuguese, where "albino" meant a white or pale-coloured person or animal, derived from "albus", the Latin word for white. English picked it up in the 18th century, and it was used first for white animals and plants before it came to describe people with a pigment disorder. The suffix has a longer ancestry. The "-ism" ending descends from Ancient Greek "-ismos", a noun-forming ending that passed through Latin and French into English, where it became a productive way to name a condition, belief or practice. Attaching it to "albino" produced a name for the state of being albino, and "albinism" entered English in the 19th century, when scientists were beginning to describe the inherited condition in medical terms.

Synonyms: hypopigmentation, lack of pigment, pallor, whiteness, paleness
