obliquity
Tilt from vertical
Obliquity is the quality of being indirect or evasive, particularly in speech or reasoning: The obliquity of his answers made me suspicious.
In astronomy and geometry, obliquity refers to the angle of inclination between two planes—most notably the tilt of Earth's axis relative to its orbit, which causes the seasons.
The word suggests deviation from the straightforward or perpendicular.
