  • IPA (Ecclesiastical): [ˈaː.nus][1]

Forms

anus f (genitive anūs); fourth declension[1]

Etymology

It is inherited from Proto-Italic *anu- (“old woman”), inherited from Proto-Indo-European *h₂enH-o- (“old woman”), perhaps a nursery word.[2] Cognate with Hittite 𒄩𒀭𒈾 (ḫanna-, “grandmother”), Old Armenian հան (han, “grandmother”), Lithuanian anyta (“mother-in-law”) and Old High German ana (“grandmother”).[2][3] Why it became a u-stem is unclear; de Vaan suggests the influence of nurus “daughter-in-law”.[2]

Earliest recorded meaning

Köbler dates it from Ennius, whose Annales have an old woman bringing a light on trembling limbs; de Vaan dates it from Plautus.[4][3][2] Köbler dates Ennius 204–169 BC.[4]

Semantic evolution

It meant an old woman, the counterpart of senex “old man”, and Döderlein notes that it was used both with respect and as a reproach for weakness, credulity or talkativeness.[3][5] Horace uses it of a sorceress, and it was also used as a feminine adjective, “old, aged”, of women, animals and things, as Plautus' rich old wife.[3][6]

The diminutive anicula “little old woman” and the adjective anīlis “of an old woman” belong to it, and the Appendix Probi insists on anus, not a diminutive anucla.[7][3]

Usage notes

Ānus, ānī (long ā), masculine, is a different word: “ring, link”, then “anus”, from Proto-Indo-European *h₁eh₂no- (“ring”), and Cicero discusses it as an indecent word, and it gave English anus in the 1650s.[2][3][8] Döderlein contrasts anus, an old lady, with vetula, an old woman as decrepit.[5]
