Forms

īnsufficiēns (genitive īnsufficientis); third-declension one-termination adjective[1][2]

Etymology

It is from Latin in- + sufficiēns (“sufficient”),[3][4][5] the negative prefix with the present participle of sufficiō (“to be enough”).[6][1]

Earliest recorded meaning

It first appears in Tertullian's treatise against Hermogenes, which asks whether the divine power was “insufficient” to produce all things (nisi sī īnsufficiēns fuit dīvīna virtūs).[3][4][6]

Semantic evolution

Lewis & Short mark it as Late Latin.[4] The TLL divides its uses into persons, such as a ward judged unable to manage without curators, and things, such as thanks that fall short.[3] Medieval writers used it of persons unfit for a task, of inadequate things, of a defective argument or legal case, and of God in arguments about his omnipotence.[7][8] The adverb īnsufficienter appears in Ambrosiaster.[3] English insufficient, from the late 14th century, comes from Old French or directly from Latin, and was first used of persons.[5]
