Forms
mediu adjective m or n (feminine singular medie, plural medii); noun n (plural medii)[1][2] An older adjective meziu, plural mezi or mezii, occurs in Odobescu: „Unul de vârstă mezie, purtând îmbrăcăminte ungurești” “one of them of middle age, wearing Hungarian dress”.[3][4] The noun also had a rare variant medium.[3]
Etymology
The adjective is borrowed from Latin medius (“middle”).[4][3][2][1] Gabinschi takes it from Latin with Italian medio as a model, and DLR and MDA2 compare mezzo for the older form meziu.[5][4][3] The noun is borrowed from Latin medium (“the middle, centre”), the neuter of the same adjective used as a noun.[2][4][6] Ciorănescu dates the noun to the 18th century.[7] The Latin adjective goes back to Proto-Italic *meðios and Proto-Indo-European *médʰyos (“between”), and is cognate with Ancient Greek μέσος (mésos) and Gothic 𐌼𐌹𐌳𐌾𐌹𐍃 (midjis).[1][8]
Romanian also kept the Latin word by inheritance as miez “core, kernel”, which is thus a doublet of this word.[1][5]
Earliest recorded meaning
Ciorănescu dates the noun to the 18th century.[7] The adjective is first recorded in Budai-Deleanu's Romanian–German lexicon, which Tiktin and MDA2 date to 1818.[9][3] Negulici in 1848 defines the noun as a means of reconciliation, a middle term, the middle and a compensation.[10]
Semantic evolution
The noun first meant “middle” and “means”, Ciorănescu's “mediation”.[10][7] MDA2 dates its main modern sense, the surroundings in which living things are found, to Laurian and Massim's dictionary of 1871, and DLR quotes it from Anghel, Marinescu and Babeș, with mediu de cultură “culture medium”.[3][4] The social sense “milieu, the society one lives in”, the physical sense “medium in which a phenomenon takes place” and the spiritualist medium followed.[2][3]
Laurian and Massim give the adjective with the alternative pronunciation miediu.[11] It is used in school and logic terms: învățământ mediu “secondary education”, termen mediu “the middle term of a syllogism”, and, in the plural mezi, the middle terms of a proportion in mathematics.[4][2] Figuratively it means “moderate, balanced”.[2][12]

Usage notes
DEX 2009 has two headwords: mediu¹, the noun from Latin medium, and mediu², the adjective from Latin medius.[2] Since medium is the neuter of medius, they are one Latin word, and this entry covers both.[6] The feminine medie is also a noun, “average, mean”, as in în medie “on average”.[2] Evul Mediu is “the Middle Ages”.[13]
