Forms

imperītia f (genitive imperītiae); first declension[1] It is also spelled inperītia.[2][3]

Etymology

It is from Latin imperītus (“inexperienced”) + -ia.[2][1] imperītus is the negative of perītus (“experienced, skilled”),[4] which de Vaan files with experior and reperiō under pariō, tracing the family to Proto-Italic *per(e)i- and Proto-Indo-European *pérh3-i- (“to provide”).[4]

Earliest recorded meaning

Köbler and Lewis & Short record it first in Sallust,[5][3] who in the Jugurtha has Jugurtha learn of the vanity and inexperience of a legate, cognita vanitate atque imperitia legati.[3]

Semantic evolution

It means lack of skill or experience, ignorance.[2] Lewis & Short note that it is mostly post-Augustan and absent from Cicero and Caesar.[3] Besides Sallust it is found in Tacitus, of the inexperience of young men, in Quintilian, who couples it with boorishness, and in Pliny the Elder;[3] Seneca and Gellius use it with a genitive of the thing one is ignorant of, and Gellius even has a plural.[6][3] In Church Latin it is ignorance or lack of knowledge,[7] and medieval writers keep the classical sense, also in an author's modest remarks about his own lack of skill.[8][9]
