Lewis & Short

Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.

fundāmen, ĭnis, n. [2. fundo], a foundation (poet. for the class. fundamentum; mostly in plur.): ponere fundamina, Verg. G. 4, 161: Siculae terrae, Ov. M. 5, 361: rerum, id. ib. 15, 433; id. F. 4, 835.
In sing.: fundamine magno res Romana valet, Ov. M. 14, 808; Hier. Gal. 4, 1; 2.
