Etymology

PIE word
*h₂ékʷeh₂

Learned borrowing from Late Latin terraqueus + English -ous (suffix denoting the presence of a quality in any degree, usually an abundance). Terraqueus is derived from Latin terra (dry land; earth, soil) (ultimately from Proto-Indo-European *ters- (dry)) + Late Latin aqueus (aqueous; watery) (from Latin aqua (water) (ultimately from Proto-Indo-European *h₂ékʷeh₂ (water)) + -eus (suffix forming adjectives from nouns denoting the sources of attributes)).[1]
