indifferentia f (genitive indifferentiae); first declension[1]

Etymology

It is from Latin indifferēns (“not differing”) + -ia.[2][3]

Earliest recorded meaning

Aulus Gellius (c. 165 AD) uses it of two words that mean the same thing,[4][3] and of the variable quantity of a syllable.[2]

Semantic evolution

The declamations ascribed to Quintilian use it of twins that cannot be told apart.[2] In Christian Latin it named the quality of things that are neither good nor bad, as in Ambrose,[5] and Augustine uses it of Jovinian's teaching on the equal standing of marriage and virginity.[5] The Latin Irenaeus speaks of the indifference of the Cynics, the attitude of one who cares little for things.[5] Metricians such as Marius Victorinus used it for a syllable that may be long or short.[5]

In medieval philosophy and theology it meant equality or sameness, as of the Father and the Son, and also indeterminacy, ambivalence and indifference.[6] English indifference (mid-15th century) comes from it.[7]
