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.

exscensĭo (excens-), ōnis, f. [escendo, II.; cf. ex, IV. B. 2.], a debarkation, landing; usu. with facere (repeatedly in Liv.; elsewh. rare; not in Cic. or Caes.): quinqueremibus septem profectus ad Erythras exscensionem fecit, Liv. 28, 8, 8; 8, 17, 9 Drak.; 21, 51, 5; 22, 20, 4 et saep.
In plur.: priusquam in continentem excensiones faceret, Liv. 22, 31, 2; 29, 28, 5.
