What does slantwise mean?
Slantwise means in a diagonal or oblique direction, at an angle rather than straight ahead or straight across. It can describe the orientation of an object, the route taken by something, or the direction of a line or movement. For example, a ladder might lean slantwise against a wall, while a path might run slantwise across a field. The word has a somewhat literary and precise character, so in ordinary conversation people usually say diagonally instead. It is especially useful when the direction matters and “across” or “at an angle” might be less exact. Slantwise can also suggest a pronounced diagonal orientation, giving it a slightly more vivid quality than the neutral diagonal.
