refōrmātiō f (genitive refōrmātiōnis); third declension[1]
Etymology
It is from Latin refōrmō + -tiō, a noun of action from the verb meaning “to reshape, transform”.[2][1][3] The verb is formed from re- and fōrmō (“to shape”), from fōrma (“form, shape”);[4][5] for ⟨fōrma⟩ de Vaan considers a dissimilated older ⟨*morma⟩ and a possible borrowing shared with Ancient Greek μορφή (morphḗ, “form, shape”), and leaves the question open.[5]
Earliest recorded meaning
Seneca has it in the moral sense, the reform of character (reformatio morum) in his letters to Lucilius.[2][6][7]
Semantic evolution
It was a rare word in Classical Latin.[6] Besides Seneca's moral reform, Apuleius used it in his Metamorphoses of a bodily change, a metamorphosis into an ass.[2][6] The glossaries give it as an equivalent of Ancient Greek μεταμόρφωσις (metamórphōsis).[3]
The TLL notes that after Seneca and Apuleius it occurs above all in Christian writers,[3] and Augustine used it of renewal.[8] In medieval Britain it was the amendment or reform of a church or monastery, a frequent term in visitations from the 13th century,[9] and in Italy it also named a civic ordinance.[10] English borrowed it in the late 14th century as reformation.[4]
