Definition and Meaning of "No One"

Before we define the compound word as a whole, let’s break it down and define each word first.

It also means “used as a function word to emphasize a following negative or to introduce a more emphatic, explicit, or comprehensive statement,” “used as an interjection to express surprise, doubt, or incredulity,” “used in combination with a verb to form a compound adjective,” and “in negation.”

As an adjective, the word means: “not any,” “hardly any: very little,” “not a: quite other than a,” and “used in combination with a noun to form a compound adjective.”

The noun can be defined as: “an act or instance of refusing or denying by the use of the word no: denial,” “a negative vote or decision.”

The Merriam-Webster definition of the word ‘one’ is: “being a single unit or thing,” “being one in particular,” “being preeminently what is indicated,” “being the same in kind or quality,” “constituting a unified entity of two or more comparisons,” “being in agreement or union,” “some,” and “being a certain individual specified by name.”

As a noun, it’s defined as: “the first whole number above zero,” “the number denoting unity,” “the first in a set or series > often used with an attributive noun,” or “an article of clothing of a size designated one,” “a single person or thing,” and “a one-dollar bill.”

As a pronoun, its definition is: “a certain indefinitely indicated person or thing,” “an individual of a vaguely indicated group: anyone at all,” “used as a third person substitute for a first-person pronoun,” and “a single instance of a specified action.”
