What does narrow mean?
Narrow describes something that is limited in width, scope, range, or degree. It may describe a physically confined space, such as a narrow road or passage, but it is also widely used for restrictions on thought, opportunity, or interpretation. A narrow margin is a very small advantage; a narrow definition or argument is a strict or tightly limited one. As a verb, narrow means to reduce a difference or make something more restricted, as in “to narrow the gap.” The noun is uncommon in general use but can refer to a narrow passage or channel, particularly in the plural “the narrows,” a geographic term for a constricted stretch of water. The word is especially useful because it applies both to literal physical space and to abstract limitations, while the related adverb “narrowly” describes the manner of focusing or acting within a limited scope.
Limited in width, scope, range, or degree; restricted or closely defined.
"The passage is too narrow for large vehicles."
Beyond physical descriptions, it commonly conveys restriction, limited opportunity, or a strict interpretation.
To make or become narrower, more limited, or more restricted.
"The research helped narrow down the possible causes."
Often used with “down” or “gap” when referring to reducing a difference or range.
A narrow passage, channel, or constricted part of a body of water.
"The boat passed safely through the narrows."
This sense is relatively uncommon and is especially associated with geographical and nautical contexts.
Used mainly in the plural for a narrow stretch of water or a constricted passage.
"The ship entered the narrows at dawn."
Narrow began with the idea of strictness: its Old English ancestor could mean “precise” or “detailed” long before it became the everyday opposite of wide.
