Etymology

Noun

Middle English pupille "a child under the care of a guardian," from early French pupille (same meaning), from Latin pupillus "a boy under the care of a guardian" and pupilla "a girl under the care of a guardian"; pupillus derived from pupus "boy"; pupilla derived from pupa "girl, doll" — related to pupil entry 2

Noun

derived from Latin pupilla "pupil of the eye, girl under the care of a guardian," literally, "little doll," derived from pupa "doll, girl"; so called because the tiny image of oneself seen in another's eye is like a tiny doll

Word Origin

If you look into another person's eye, you can see a small reflection of yourself. That small image made the ancient Romans think of a doll. Thus, they called the part of the eye in which it appears the pupilla. This word literally meant "little doll." The English word for that part of the eye, pupil, can be traced to the Latin pupilla. Pupilla also had another meaning. A little girl who was an orphan and was in the care of a guardian was called a pupilla. A little boy in the same situation was called a pupillus. From these two Latin words we get the other English pupil, meaning "a young student in the care of a tutor or in school."
