mediō (present infinitive mediāre, perfect active mediāvī, supine mediātum); first conjugation[1]
Etymology
It is from Latin medius (“middle”).[2][3][4] Wiktionary describes it as a Late and Vulgar Latin verb in -iō.[1] The adjective goes back to Proto-Italic *meþio- and Proto-Indo-European *medhi-o- (“middle”).[5]
Earliest recorded meaning
The TLL finds it from the Itala and the Latin Irenaeus on, mostly as the participle mediante;[3] in Apicius it means to halve something.[2][4][6]
Semantic evolution
Used intransitively it meant to be in the middle,[2][7] above all in the participle: Palladius uses it for the middle of a month,[4][6] and the Vulgate's die festo mediante means “when the feast was half over”.[4] The participle could also mean coming between, and Sidonius and Augustine use the verb of interceding or mediating.[4][6] The TLL notes that mediante often turned into a preposition, “by means of”, as in French moyennant and Italian mediante.[3] The deponent medior is also found.[3]
A Neo-Latin description of Muscovy uses it for an open field lying between two streets.[8] Wiktionary lists Portuguese mear and French moyer among its inherited descendants.[1] English mediate comes from its past participle, first in the 1540s sense “divide in two”.[9]
