Pronunciation

  • Classical: [tɛrˈreː.nʊs][1]
  • Ecclesiastical: [terˈrɛː.nus][1]

Forms

terrēnus (feminine terrēna, neuter terrēnum); first/second-declension adjective[1]

Etymology

It is from Latin terra (“earth, land”) + -ēnus.[2][1][3] De Vaan derives terra from Proto-Italic *tersā- (“earth”) and Proto-Indo-European *ters-h₂- (“dry land”), from the root ⟨*ters-⟩ “to dry out”, so that the word first meant “dry land”.[4] He reports Nussbaum's suggestion that the adjective was made from a locative ⟨*terrai⟩ “on the ground”;[4] Wiktionary also gives a possible Proto-Italic ⟨*terzeznos⟩ built directly on the neuter s-stem.[1]

Earliest recorded meaning

De Vaan dates it from Lucretius,[4] and Köbler lists Cicero among its first authors.[3] Cicero opposes moisture of the sea and of the land, marinis terrenisque umoribus, and divides animals into those of the land and those of the water.[2]

Semantic evolution

Its first sense is “of the dry land” as opposed to the sea, then “of the ground”.[2] Caesar has an earthen mound, tumulus terrenus, and Livy uses the neuter terrenum as a noun for soil that can be ploughed.[2][5] Ovid has a furnace of baked clay.[2] In philosophy it is what consists of earth as one of the four elements, and Cicero applies it to the material, mortal part of man.[2] Apuleius and Lucan use it of the earth or the known world as against the heavens, “earthly”.[2] In Church Latin it is the earthly and transitory as opposed to the eternal, with terrēna “earthly things”,[6] and medieval writers use it for what belongs to this world and this life.[7] English took terrene about 1300, and terrain came in 1727 through French from the neuter used as a noun.[8]
