Leaning or inclined at an angle rather than being vertical or flat.
From 'slope,' which entered English in the 1600s, possibly from Dutch 'slopen' or Scandinavian origins. The exact origin is debated but may relate to 'sloop' (a sailing vessel).
Interestingly, 'slope' has no clear agreed-upon origin—linguists think it might come from old sailing terminology since ships tilt and lean, but nobody's completely sure!
