Forms

fundāmentum n (genitive fundāmentī); second declension[1]

Etymology

It is from fundō “to lay the bottom of, found” with the suffix -mentum.[2][1][3] ⟨Fundō⟩ is from fundus “bottom”.[1][4] Isidore says it is so called because it is the ⟨fundus⟩ of the house.[5]

Earliest recorded meaning

The OLD's earliest citations are from Plautus, of the foundation of a house and figuratively of a basis.[2] Köbler dates Plautus c. 250–184 BC.[6]

Semantic evolution

It meant the substructure of a building, a foundation, mostly in the plural, as Cicero's fundāmenta agere and Virgil's fundāmenta locāre, and ā fundāmentīs dīruere was to raze to the ground.[2][7][8] Figuratively it meant that on which a thing rests, a basis, and in Varro a fundamental necessity; poets use it of something founded, as Saguntum.[2] Manilius uses it apparently of the nadir in astrology.[2]

In Ecclesiastical Latin it meant foundation, base, establishment, and Isidore applies it to Christ, on whom the Church is built.[9][5] Old French fondement gave English fundament in the late 13th century, meaning both “foundation” and “buttocks”.[4]
