Forms

incapābilis (neuter incapābile); third-declension adjective[1][2]

Etymology

It is from Latin in-2 + capābilis (“that can be grasped”),[3][4] formed after Greek ἀχώρητος (akhṓrētos), which the glossaries give as its equivalent.[3][1]

Earliest recorded meaning

The Latin translation of Irenaeus says of the Father that he was without beginning and incomprehensible (sine initio et incapabilis);[3] the first dated author to use it is Augustine, in a sermon.[2][5][4]

Semantic evolution

In Christian writers it meant that cannot be grasped or contained, said above all of God and his nature, sometimes with a dative.[3][1] Lewis and Short also cite it from an Arian quoted in Augustine's letters.[1]

Medieval Latin kept the sense “incomprehensible”[6][7][8] and also used it of what cannot be taken in or received by something: Gerhoh of Reichersberg writes that the eternity and immensity of the divine nature cannot be received by human nature.[9]
