in nautical terminology, a deck or part of a ship located forward of the main orlop deck.
From 'fore-' (before/forward) combined with 'orlop' (the lowest deck of a ship, from Dutch 'overloop' meaning 'to run over'). This is highly specialized ship terminology.
Ship terminology is a graveyard of incredible compound words—'foreorlop' is obscure today because wooden ships are gone, but maritime English created whole vocabularies for now-vanished structures.
