Forms

Etymology

It is formed from Latin incapāx (“unable to hold, incapable”) + -tās.[3][2]

Earliest recorded meaning

Filastrius of Brescia uses it in his book of heresies: the Son of God put on flesh because of our incapacity to see him.[3]

Semantic evolution

Rufinus, translating Origen, speaks of the incapacity of the hearers.[3][1][4] In British medieval Latin it came to mean a want of legal ability or qualification, for instance of clergy to hold temporal property, and also a want of understanding;[5] a Hungarian charter uses it for the unsuitability of a time,[6] and Czech sources for slowness of mind.[7] English took incapacity in the 1610s from French, which goes back to the Medieval Latin word.[8]
