Forms

indīvīsibilis (neuter indīvīsibile); third-declension two-termination adjective[1][2]

Etymology

It is formed from Latin in-2 (“not”) + dīvīsibilis (“divisible”),[3][4] the adjective of possibility made from dīvidō (“to divide”).[4]

Earliest recorded meaning

The TLL records it from Tertullian on;[3] in his treatise De anima he calls the soul indivisible, anima indivisibilis.[1][3]

Semantic evolution

A post-classical word,[1] it was used by the grammarian Diomedes of matter and by Isidore of Seville.[1][2] Bede uses it to explain the Greek word for the smallest, undividable unit of time,[5] and in medieval philosophy and theology it became a common term for what cannot be divided, applied to unity and to God and the Trinity.[5][6] Thomas Aquinas distinguishes several ways in which a thing can be called indivisible.[7] Medieval Latin also used it for inseparable,[8][5] and in charters for property held undivided in common.[9][6]

English borrowed the word in the early 15th century, from Old French and directly from Late Latin.[10]
