Pronunciation

  • Classical: [prɛˈkaː.ri.ʊs][1]
  • Ecclesiastical: [preˈkaː.ri.us][1]

Forms

precārius (feminine precāria, neuter precārium); first/second-declension adjective[1] Also spelled -eus.[2] Inscriptions also have praec-.[3]

Etymology

It is from Latin prex (“prayer, request”) + -ārius.[2][1][3]

Earliest recorded meaning

Köbler dates it from Cicero,[4] but Lewis & Short think Cicero used it perhaps only as the adverb precāriō “by request”, which Plautus and Terence already have, and find the adjective frequent only from the Augustan period.[5] Livy writes of help not merely begged as a favour but claimed as a due.[5]

Semantic evolution

It is what is given as a favour or held on sufferance, depending on another's goodwill: Livy has a tribune's power bringing help granted by favour rather than by right, and Tacitus a life held on sufferance.[2][5] Ovid uses it of a borrowed form.[2] In law the neuter precārium is something granted at request for as long as the grantor allows, and the adjective concerns tenancy at will.[2][5] From this it comes to mean uncertain, insecure, precarious: the elder Seneca speaks of a priestess whose chastity is precarious, and Seneca the philosopher of the wise man counting his body among precarious things.[2][5] Words may be ambiguous, and Fronto has a shaky writing hand.[2] In Medieval Latin it concerns the precarial grant.[6] Church Latin glosses it uncertain, precarious.[7] English precarious (1640s) was first a legal word, held through the favour of another.[8]
