limit (lĭm'ĭt) Pronunciation Key
A number or point for which, from a given set of numbers or points, one can choose an arbitrarily close number or point. For example, for the set of all real numbers greater than zero and less than one, the numbers one and zero are limit points, since one can pick a number from the set arbitrarily close to one or zero (even though one and zero are not themselves in the set). Limits form the basis for calculus, where a number L is defined to be the limit approached by a function f(x) as x approaches a if, for every positive number ε, there exists a number δ such that |f(x)-L| < ε if 0 < |x-a| < δ. |
the limit
The most extreme; someone or something that irritates, delights, or surprises to the ultimate degree. For example, Hiring and firing someone the same daythat's the limit in employee relations! or That excuse of yours for missing the wedding, that's the limit, or He's done wonders before but this last one is the limit. This idiom uses limit as "the last possible point or boundary." [Colloquial; c. 1900]
