Pronunciation

Forms

perīculum n (genitive perīculī); second declension[1]

Etymology

It is from an unattested verb ⟨*perior⟩ “to try”, seen in experior and perītus, with the suffix -culum.[2][3] Wiktionary derives it from a Proto-Italic ⟨*per-ei-klom⟩, from an ⟨i⟩-present of Proto-Indo-European *perh₃- (“to go through, attempt”), and the OLD compares Ancient Greek πεῖρα (peîra, “trial”).[1][2] The contracted ⟨perīclum⟩ is regular in the comic poets and frequent in later poetry.[2][4]

Earliest recorded meaning

The OLD's earliest citations are from Plautus, of a trial and of danger.[2] Köbler dates Plautus c. 250–184 BC.[5]

Semantic evolution

It meant a test, trial, proof, usually perīculum facere “to make trial of”, as in Plautus and Cicero.[2][6] From Plautus it meant liability to harm, danger, and in Cicero the situation of a party in a lawsuit.[2] From Terence it meant the responsibility for a loss, liability, meō perīculō “at my own risk”.[2] Döderlein contrasts perīclitārī, to make trial boldly despite the danger, with tentāre, to test from a wish to know.[7]

In Ecclesiastical Latin it meant danger, trial, peril, attempt, experiment.[8] Medieval Latin used perīculum animae for damnation, and perīculum gradūs for loss of rank.[9] It survives in French péril, Spanish peligro and Portuguese perigo, and Old French peril gave English peril about 1200.[1][10]
