Pronunciation
Forms
magnus (feminine magna, neuter magnum, comparative maior, superlative maximus or maxumus, adverb magnopere); first/second-declension adjective[1]
Etymology
It is inherited from Proto-Italic *magno- (“great”), inherited from Proto-Indo-European *m̥ǵ-no- (“great”), from the root *meǵh₂- (“great”).[2][1] The comparatives maior and magis and the superlative maximus come from the same root with the suffix *-is-.[2]
Cognate with Oscan mais (“more”) and Umbrian mestru (“greater”),[2] and further with Hittite mekki- (“much, many”), Sanskrit महि (máhi-, “great”), Ancient Greek μέγας (mégas, “great”), Gothic 𐌼𐌹𐌺𐌹𐌻𐍃 (mikils, “great”) and English much.[2][3]
Earliest recorded meaning
It appears in the Laws of the Twelve Tables.[2][4] Livius Andronicus speaks of mare magnum, “the great sea”.[3]
Semantic evolution
It meant great in size, as Ennius' great oaks, and great in number or amount, as Plautus' great harvest.[3] The ablative magno meant “at a high price”, magna voce “in a loud voice”, and it was used of strong winds.[3] Added to a name it meant “the Great”, as in Pompey's cognomen, and in kinship it meant “great-”, as magna amita “great-aunt”.[3]
Figuratively it meant great in degree, difficult, important, and of people eminent, powerful or distinguished.[3] Magno animo was “with a bold or noble spirit”, and it could also mean proud or boastful.[3] Medieval Latin used it in names such as Carolus Magnus, Charlemagne.[1] English magnitude comes from its derivative magnitudo.[5]

Usage notes
Döderlein groups magnus, grandis and amplus, a fitting greatness, against ingens, immanis and vastus, an overwhelming one, and notes that magnus is greatness with no further shade of meaning.[7]
