Forms

inclīnātiō f (genitive inclīnātiōnis); third declension[1]

Etymology

It is from Latin inclīnō (“to bend, incline”) + -tiō.[2][3][1] A gloss of Jerome explains the name Lot as “inclination”.[3]

Earliest recorded meaning

The TLL lists it in Varro, Cicero and Livy,[3] and Köbler dates it from Cicero,[4] who uses it of the swerve of the atoms in On the Nature of the Gods and lists it among the movements of the body.[2][5]

Semantic evolution

Its basic sense is a leaning, bending or tilting to one side, of the body, a battering ram or a ship, and a downward movement.[2][5] Vitruvius uses it of slope or obliquity, and of the inclination of the sky, which he says the Greeks call klimata.[2] Figuratively it is a tendency or inclination of the feelings and will, as Cicero hopes a judge will lean towards his side, of circumstances and of character.[2][5] It is also a change or turn in events, as Cicero's sudden shift of feeling at the consular elections, often a change for the worse.[2] Church Latin glosses it tendency, inclination,[6] and Medieval Latin uses it of condescension and of subjugation.[7] English inclination (late 14th century) comes from French and directly from Latin.[8]
