Forms

aedituus m (genitive aedituī); second declension[1] The Acts of the Arval Brothers have the accusative aedituon, and an inscription the genitive plural aedituom.[2]

Etymology

It is from Latin aeditumus (“temple keeper”), the older form, through the loss of its ⟨m⟩,[2][3] and was the commoner form in everyday speech.[2] The OLD analyses aeditumus as a derivative of aedēs (“temple”) with the suffix -timus,[3] and de Vaan lists both forms among the derivatives of that noun.[4] Lewis & Short and Wiktionary instead take the word as a compound of aedis and tueor (“to watch over”).[5][1]

The Romans themselves connected it with guarding: Varro derives the older form from guarding the temple,[6] and Gellius calls the keeper aedituus as if named from looking after temples.[5]

Earliest recorded meaning

Plautus has it first, in the Curculio, for the keeper of a temple.[2][7][8]

Semantic evolution

Varro rejected the form aedituus in favour of aeditumus,[2] but it became general in the written language from Livy on.[2] The keepers also showed visitors round the temple, so Horace calls the poets the aeditui of virtue, those who display its worth.[5] In the Vulgate the plural means priests or ministers of a sanctuary,[5] and Ecclesiastical Latin uses it for a sacristan, caretaker or warden.[9][1] Medieval sources use it for a custodian in a house of canons, a sexton, and once a herald.[10]
