means A single human being considered on their own, apart from the group — one distinct person.

from From Latin individuus, 'not divisible' — in- (not) plus dividuus (divisible, from dividere, to divide). Medieval thinkers used it to mean something that couldn't be split into smaller parts, the atomic unit of a kind. By the 1600s English writers started applying it to a single human person — the idea being that a person, like an atom, was the indivisible unit society was built from. The irony baked into the word from the start: it was coined to mean 'cannot be split,' and now describes the one thing that insists on splitting itself off from everyone else.
