Pronunciation

  • IPA (Classical): [deːˈkliː.noː][1]
  • IPA (Ecclesiastical): [deˈkliː.no][1]

Forms

dēclīnō (present infinitive dēclīnāre, perfect active dēclīnāvī, supine dēclīnātum); first conjugation[1]

Etymology

It is from dē- “down, away” and ⟨*clīnō⟩ “to bend, incline”, found in acclīnō, related to Ancient Greek κλίνω (klínō, “to bend”).[2][1][3]

Earliest recorded meaning

Gaffiot cites Plautus, sē dēclīnāre extrā viam “to turn aside from the road”.[4] Köbler dates Plautus c. 250–184 BC.[5]

Semantic evolution

It meant to turn aside, deflect, divert, and intransitively to deviate, swerve, as in Cicero and Lucretius; to tilt downwards, as in Vitruvius; and in Apuleius to sink down.[2][4] Cicero also used it for avoiding or dodging something and for stepping aside from a course of conduct.[2] In grammar, from Varro on, it meant to change the form of a word, to inflect.[2]

In Ecclesiastical Latin it meant to incline, lean to one side, step aside, turn away.[6] English decline came through Old French decliner in the late 14th century.[7]
