Pronunciation

  • Classical: [ˈaɫ.tɛ.roː][1]
  • Ecclesiastical: [ˈal.te.ro][1]

Forms

alterō (present infinitive alterāre, perfect active alterāvī, supine alterātum); first conjugation[1]

Etymology

It is from Latin alter (“other”) + -ō, “to make other”.[1][2][3][4]

Earliest recorded meaning

Its first example is in the medical writer Caelius Aurelianus, who uses it in a warning not to alterent a cough rather than soothe it: to make worse, the opposite of mītigāre.[2][3][5]

Semantic evolution

Boethius uses it in his commentaries on Porphyry and Aristotle's Topics for making something different: everything that is other has been altered, he writes, but not everything that has been altered can be called other.[2][3][4]

In Medieval Latin it became the usual verb for change of quality in natural philosophy: Albertus Magnus uses it of the senses, of bodies and of food altered by digestion.[6] British sources use it of changing things in general, of distinguishing, of doubling the length of a note in music, and, with habitus, of taking the monk's habit.[7] Through Old French alterer it became English alter in the late 14th century.[8]
