Litus (-oris, n.) est finis maris vel oceani,^[1] regio continentis vel insulae ubi aqua et terra conveniunt,^[2] vel linea quae fines terrae et oceani vel lacús est.^[3] Exactus autem linea quae linea litoralis vere appellari potest paradoxi litoralis causa determinari non potest.

Litus pelagicum est litus quod oceano aperto adiacet, contra regionem protectam in sinu vel portu; ora autem est regio quae alicui magno corpori aquae adiacet, oceanis lacubusque non exceptis.
