Word Nuance & Usage

In strict mathematical geometry, a square is considered a special type of rectangle where all four sides have equal length, whereas in everyday language 'rectangle' usually refers specifically to an oblong figure whose adjacent sides are unequal.

Word Origin & Etymology

Borrowed in the late 16th century from Middle French rectangle, from Medieval Latin rectangulum, a compound of Latin rectus ('straight' or 'right') and angulus ('corner' or 'angle').
