An endowment fund is a lasting fund established for a specific purpose. Normally, the recipient can only access income from the investments of the account. There are thus limitations on withdrawing from the Principal endowments.
Also an endowment is a charitable donation in the form of real property, assets, or funds, usually given to an institution to support a specific goal. Typically, the principal of the endowment is invested, and the interest is used to fund projects. Endowment can also refer to the innate capacities of an individual, group, or institution.
