What does limit mean?
A limit is a boundary, maximum, or restriction that determines how much of something is allowed or possible. It can refer to a measurable threshold, such as a speed limit or spending cap, as well as to an abstract boundary that marks the point beyond which a person or process cannot continue. In everyday language, limits often describe physical capacity, tolerance, or opportunity: a speaker reaches the limit of an audience’s attention, or a service imposes limits on access. As a verb, to limit means to restrict quantity, range, or possibility, often for a practical or regulatory reason. The word is useful because it applies both to precise numerical constraints and to the broader boundaries of what can be achieved, experienced, or accepted.
The greatest or smallest amount, degree, or extent allowed or possible; a boundary or restriction.
"The amount of water available is limited by the dry season."
In the plural, limits can mean personal boundaries or the limits of a person’s ability or circumstances.
To restrict the amount, size, range, or extent of something.
"The new policy limits the number of applicants each school may accept."
Common in formal, technical, legal, and everyday contexts; it does not necessarily imply that the restriction is unreasonable.
The plural commonly refers to personal, practical, or physical boundaries, as in “know your limits” or “the limits of human endurance.”
"The climb tested the limits of the hikers’ endurance."
From the Latin word for a threshold, limit began as a doorway: a precise place where one space ends and another begins.

Etymology of limit
The word comes through late Middle English from Old French limite, ultimately from Latin limes, meaning “boundary” or “threshold.” The related Latin limen, meaning “threshold,” also gives rise to words such as eliminate and subliminal. English initially used the noun for a boundary or limit, and the verb developed the meaning of restricting or bounding something.
