Are there imperfect squares?

I think the term is used to distinguish a number that is a square of a whole number (perfect) vs. a square of some other number (I don't know if they are called imperfect though).  Most whole numbers appear to be squares of irrational numbers, like 2 is a square of the square root of two.  (Here irrational means "unable to be expressed as a ratio".)
