There's the technical definition where rectangle is a genus of the species square, and there's the colloquial definition - if there are two boxes and one is a cube and the other is elongated, most people will ask for "the rectangular" one and not the "non square" one.
And an important part of life is learning when to pick your battles.
>where rectangle is a genus of the species square
Wrong battle, I know, but to nitpick the species is more likely quadrilateral.
Quadrilateral would be the family, and rectangle the genus, square the species. Or you could promote quadrilateral to order and designate parallelogram the family.
I thought polygons as the family ...
