square root
One definition of "root" is "the basic cause, source, or origin of something." The source of a perfect square is the number that was multiplied by itself to create it: the root of the square, the square root.
A number will have both a positive and negative square root 5 x 5 = 25 and -5 x -5 = 25.
The antonym of "invariably" is "variably." While "invariably" means something that occurs consistently or without exception, "variably" indicates something that can change or is subject to variation. Other possible antonyms include "occasionally" or "sporadically."
