Pronunciation
Forms
medius (feminine media, neuter medium, comparative magis medius or medior, superlative medioximus); first/second-declension adjective[1]
Etymology
It is inherited from Proto-Italic *meþio-, inherited from Proto-Indo-European *medʰi-o- (“middle”).[2] Wiktionary gives the Proto-Italic as *meðios and the PIE as *médʰyos (“between”).[1] Cognate with Oscan mefiaí (“in the middle”) and South Picene mefiín,[2] and with Ancient Greek μέσος (mésos), Sanskrit मध्य (mádhya) and Gothic 𐌼𐌹𐌳𐌾𐌹𐍃 (midjis).[3][1][4] De Vaan derives dīmidius “half” from it, with the prefix dis-.[2]
Earliest recorded meaning
De Vaan records it from Livius Andronicus onwards, in the sense of “middle, central”.[2] Köbler dates Livius Andronicus 280/260–before 200 BC.[5]
Semantic evolution
In Classical Latin it meant situated at the centre, as digitus medius “the middle finger”, and, used partitively, the middle of something: in mediō foco “in the middle of the hearth” in Plautus.[3] It also meant lying between, intervening, and in time the middle of a period: nox media “midnight”, diēs medius “midday”.[3] From this came the senses moderate, middling, ordinary, and of persons neutral, committed to neither side, as when Cicero says it will no longer be allowed to stay neutral.[3] It could also mean acting as an intermediary between two parties.[3] Döderlein contrasts the purely local medius with modicus “moderate in quantity” and mediocris “middling in worth”.[6]
In medieval Latin it formed legal phrases of the vineyard contract ad medium plantum.[7] Its Romance descendants include Italian mezzo, Portuguese meio, Romanian miez and French mi-, while English media and English medium go back to its neuter.[1][8]
