Limit (noun) — a point, line, or level beyond which something cannot or must not go; a maximum amount or value that is permitted or possible. Example: There is a time limit of thirty minutes for the test.
Limit (verb) — to set a boundary on something; to keep something within fixed bounds; to restrict. Example: Try to limit your screen time to one hour a day.
What Does Limit Mean?
Limit comes from the Latin word limes (genitive limitis), which originally referred to a boundary path or the fortified frontier of the Roman Empire. The word entered English in the 14th century through Old French limite. Over time it broadened from a physical border to any kind of maximum, restriction, or endpoint — whether that is a legal speed limit, a personal budget limit, or the outer limit of human knowledge.
In modern British English, limit is extremely versatile. As a noun it typically refers to a fixed boundary imposed by rules, circumstances, or physical reality: the speed limit, a word limit, the limits of her patience. As a verb it means to deliberately keep something below a certain level or within a defined range: to limit spending, to limit access.
Related forms to learn alongside this word: the adjective limited (restricted, not great in amount), the adverb limitlessly, the noun limitation (a weakness or constraint), and the prefix un- giving unlimited (having no boundaries). The same Latin root limes also gives English the verb eliminate — to remove something entirely, literally to "put it outside the boundary".
