one
Lowest positive integer
One is the written form of the number 1 and works as an adjective in that capacity (one window).
One substitutes for a singular noun that has been used already, or when reference is clear from context (buy one, get one free).
One is an impersonal and somewhat formal third-person singular pronoun without gender: One should be careful in that situation.
Groups of things sharing some characteristic can be designated with an adjective before ones (red ones, lucky ones).
