Etymology

Origin of breadth

1515–25; earlier bredeth, equivalent to brede breadth ( Middle English; Old English brǣdu, equivalent to brǣd-, mutated variant of brād broad + -u noun suffix) + -th ¹ ( def. ) akin to German Breite, Gothic braidei

Explanation

If you measure the distance of an object from side to side, you are measuring the object’s breadth: “Theodore measured the breadth of the table before buying it to make sure it would fit in his small kitchen.” Breadth often refers to a physical measurement, but it can also be used to describe comprehensiveness or largeness of any kind, such as breadth of knowledge or breadth of experience. In the famous sentence describing Macedonian king Alexander the Great, the word breadth is used to indicate the vastness of Alexander’s empire: “When Alexander saw the breadth of his domain he wept, for there were no more worlds to conquer.”
