Just goes to show you learn something new all the time.
7: one of two opposite directions especially of motion (as
of a point, line, or surface)
18. Mathematics. one of two opposite directions in which
a vector may point.
Paraphrasing the Collins Dictionary of Mathematics:
The sense of a vector is the sign of the measure, contrasted with the
magnitude. Thus the vectors AB and BA have the same direction but
opposite sense. Sense is also used to distinguish clockwise and anti-
Sense is, if you like, a "signed direction". "Towards north" (say) as
opposed to "along the north-south axis".
