fund

A "fund" is usually money that has been set aside for a particular purpose. A school might have a scholarship fund, a family might keep an emergency fund, and a company might create a fund for a new project. The idea is simple: the money is there to be used when needed for that purpose.

"Fund" is also often used as a verb. A government may fund public transport, a charity may fund medical research, or investors may fund a new business. In a broader and less common sense, it can also mean a supply of something useful, as in a "fund of knowledge," meaning a large store of knowledge.

The word "fund" is most often used for an amount of money kept for a special purpose. That money may belong to a person, a group, a business, or a government. You might hear about a pension fund, a relief fund, a college fund, or an investment fund. In everyday use, it often suggests planning and support: money has been collected, saved, or reserved so that something important can be paid for later.

As a verb, "fund" means to provide the money for something. A city can fund a new bridge, a charity can fund a hospital program, and a private donor can fund a piece of research. This verb is very common in news, business, education, science, and public policy, where people often talk about who is funding a project and how much support it receives.

The word also has a broader figurative use. A person may have a "fund of knowledge" or a "fund of experience," meaning a large stored supply of something valuable that can be drawn on when needed. So while the word usually points to money, its wider idea is a supply of useful resources kept ready for use.
