Plural of corral; pens or enclosures for confining livestock, or the verb meaning to gather animals into such spaces.
From Spanish 'corral,' a variant of 'corro' (circle). The term spread through English-speaking territories in the American Southwest where Spanish culture dominated.
A corral is basically a circle of fencing, and its name 'corro' literally meant 'circle' in Spanish—so the design actually fits the origin of the word perfectly.
