single

"Single" is a common word with a few clear uses. Most often, it means just one of something: a single flower, a single ticket, or a single mistake. It is also widely used for a person's relationship status, meaning not married or not in a romantic relationship. In other cases, it can describe something meant for one person, like a single room or a single bed, or something separate rather than grouped with others.

The word "single" is very flexible, but the idea at its center is simple: it points to one person or thing rather than more than one. In its most basic use, it means only one, as in "a single drop of rain," "a single serving," or "a single chance." In this sense, it often stands in contrast to double, multiple, or paired.

In everyday life, "single" is also a standard way to describe relationship status. If someone is single, they are not married, and in many contexts it also suggests that they are not currently in a romantic relationship. The exact meaning can depend on the situation, but the general idea is that the person is on their own rather than part of a couple.

The word can also describe something intended for one person or one unit, such as a single room, a single bed, or a single portion. Sometimes it means separate or not combined, as when items are sold as single pieces instead of in sets. As a noun, "single" can mean one song released on its own, especially in music. Across these uses, the word keeps the same basic idea: one, separate, or not joined with another.
