circuncribe is incorrectly written, and should be written as "it circumscribes" being its meaning:
3rd person singular of the present indicative or 2nd of the imperative of the verb circumscribe, from the latin circumscribo ( circum pontum ): describe a circle around. Geometrically wrap or include something within a circular line. Also reduce, restrict, limit, annotate something to certain terms. You can use also pronominalmente.
