Etymology

It is borrowed from French terrain (“piece of earth, ground, land”),^[2][3][4] from Vulgar Latin *terrānum, an alteration of Latin terrēnum (“land, ground”), the neuter of terrēnus (“of the earth”) (see terrene),^[2][3][4][5] from terra (“earth, land”),^[2][3] from Proto-Indo-European *ters- (“to dry”).^[3] Latin terra is cognate with Oscan teeróm (“territory”) and Old Irish tīr (“territory”).^[2]

Semantic evolution
