Description:

The internal conjunction ;jo' means 'but' or 'yet'. Both arguments are true, the second is a contrastive idea. Should not be chained. If either of its arguments is itself conjunct, the totality of one side is contrasted with the totality of the other.

Mathematics:

In maths, 'jo' is used as the particle to indicate fractions or division, where the antecedent is the numerator and the object is the denominator.
