individual

individual: [15] To begin with, individual retained in English its ancestral meaning ‘not able to be divided’: ‘in the name of the holy and individual Trinity’. Richard Whitbourne, Discourse and Discovery of Newfoundland 1623. It was borrowed from medieval Latin indīviduālis, a derivative of Latin indīviduus ‘not divisible’, which in turn was based on dīviduus, a derivative of the verb dīvidere ‘divide’. The semantic move from ‘not divisible’ to ‘single, separate’ took place in the 17th century. (English acquired the formally parallel indivisible, incidentally, in the 14th century.)
=> divide

individual (adj.)

early 15c., "one and indivisible" (with reference to the Trinity), from Medieval Latin individualis, from Latin individuus "indivisible," from in- "not, opposite of" (see in- (1)) + dividuus "divisible," from dividere "divide" (see divide). Not common before c. 1600 and the 15c. usage might be isolated. Sense of "single, separate" is 1610s; meaning "intended for one person" is from 1889.

individual (n.)

"single object or thing," c. 1600, from individual (adj.). Colloquial sense of "person" is attested from 1742. Latin individuum meant "an atom, indivisible particle;" in Middle English individuum was used in sense of "individual member of a species" from early 15c.
