obliquely = indirectly or at an angle

Definitions:

(1) (oblique as in: an oblique reference)
indirect or at an angle
(2) (meaning too rare to warrant focus)
Less commonly, oblique can have other meanings that relate to the concept of slanting:
- An oblique line is not parallel or perpendicular to its reference line.
- An oblique angle is not a right angle or a multiple of a right angle.
- An oblique muscle is one that runs at a slant relative to the long axis of the body or relevant limb--such as the abdominal obliques.
