Aid vs. Aide How to Choose the Right Word

The words aid and aide are homophones—they sound alike but have different (though related) meanings. Among all of the homophones in the English language, these are two of the most frequently confused. How to Use Aid The verb aid means to assist: to provide what is needed to achieve a goal. The noun aid refers to material assistance or to a person, organization, or thing that provides such assistance. As a noun, aid is frequently a synonym for charity, relief, or largesse. How to Use Aide An aide is a person who acts as a helper or an assistant. The word comes from aide-de-camp, a French term for a military officer who assists a senior officer. Aide is always a noun; it often refers to someone who supports an important person such as a politician or a professor. Neither aid nor aide should be confused with AIDS, which is an acronym for acquired immune deficiency syndrome. Examples Aid can be either a noun or a verb. It usually refers to some form of material support or to the act of providing such support: The United Nations called for nearly $500 million in aid for flood-ravaged Pakistan.The United Nations appealed for donations to aid flood victims in Pakistan.

How to Remember the Difference One way to remember the difference between aid and aide is that aide, like the word helper, has an e in it. If you need a helper, you are looking for an aide. An aide is always a person, usually someone whose professional responsibility is to provide assistance (or aid sans the e). In some circumstances, however, aid can refer to a person, such as in the following sentence: When I was too sick to take care of myself, my husband was a big aid to me. Aid is the appropriate word in this context because the husband was not acting in a professional capacity; he was merely the source of assistance.
