Forms

prī̆ncipium n (genitive prī̆ncipiī or prī̆ncipī); second declension[1]

Etymology

It is from prīnceps “first, foremost” with the suffix -ium.[2][1][3] Isidore applies it to the Son of God, because all things are from him and nothing before him.[4]

Earliest recorded meaning

Köbler's first source is Ennius, whom he dates 204–169 BC, and the OLD's earliest citations are from Plautus and Ennius.[3][2]

Semantic evolution

It meant a beginning, start, principium capere to begin, in principiō at first, and the point of time at which something begins, as Cicero's nec prīncipium nec fīnem habēre “to have neither beginning nor end”.[2][5] It meant an origin, the first part of a thing, the source of a river, and the opening of a speech or book, as in Plautus.[2] In philosophy the plural meant first elements of matter, and it also meant a primary cause, a guiding principle, and a premiss, as in Cicero.[2] In military language the prīncipia were the headquarters of a camp, and the second line of battle.[2] Döderlein explains that initium is the beginning as a mere starting point, opposed to exitus.[6]

In Ecclesiastical Latin it meant beginning, source, foundation, principality, origin, principle.[7] Medieval Latin used it of a master's inauguration.[8] Through Anglo-French it gave English principle in the late 14th century, first “origin, source”.[9]
