singleness

Singleness is most often the state of not being married. A person may enjoy their singleness, struggle with it, or simply see it as one part of life. In everyday use, this is the meaning most people will understand first.

The word can also mean a strong, undivided focus, as in "singleness of purpose." In older or more formal English, it can also mean sincerity, honesty, or simplicity of heart. All of these meanings grow out of the idea of being single, whole, or not divided.

The word "singleness" has a few related meanings built around the idea of being one rather than divided. Most commonly, it refers to the state of not being married. In that sense, it can describe a stage of life, a personal choice, or simply someone's present condition. A sentence like "She valued her singleness and built a full life of her own" uses the word in this everyday way.

The word also appears in more formal expressions such as "singleness of purpose" or "singleness of mind." Here, it means steady, undivided attention to one aim. It suggests concentration, directness, and freedom from distraction. This use is less common in casual speech, but it is still clear in writing and careful conversation.

An older meaning of "singleness" is sincerity, honesty, or simplicity of heart. In this sense, a person with singleness is straightforward and not double-minded. This meaning survives especially in phrases like "singleness of heart," where the word points to genuine feeling and clean intention rather than marital status.

So the word may describe being unmarried, having one clear purpose, or showing simple and sincere intent. The exact meaning depends on context, but the central idea stays the same: being single, whole, and not divided.
