"a word that asserts or declares; that part of speech of which the office is predication, and which, either alone or with various modifiers or adjuncts, combines with a subject to make a sentence" [Century Dictionary], late 14c., from Old French verbe "word; word of God; saying; part of speech that expresses action or being" (12c.) and directly from Latin verbum "verb," originally "a word," from PIE root *were- (3) "to speak" (source also of Avestan urvata- "command;" Sanskrit vrata- "command, vow;" Greek rhētōr "public speaker," rhetra "agreement, covenant," eirein "to speak, say;" Hittite weriga- "call, summon;" Lithuanian vardas "name;" Gothic waurd, Old English word "word").
mid-15c., "tillage, cultivation of large areas of land to provide food," from Late Latin agricultura "cultivation of the land," a contraction of agri cultura "cultivation of land," from agri, genitive of ager "a field" (from PIE root *agro- "field") + cultura "cultivation" (see culture (n.)). In Old English, the idea could be expressed by eorðtilþ.
