Note
A regular plural whose use depends on the meaning in play. Road junctions are counted freely: busy intersections, dangerous intersections. In set theory the singular is usually right, because the intersection of two or more sets is one set that holds every shared element. The plural belongs to comparing several such sets. Geometry works the same way: two curves may meet at several points, yet those points together make a single intersection.
