An aide is a person who assists others, while the noun aid is an inanimate object or form of relief that helps to achieve a goal. The word aid is also a verb, where it is used to describe the act of assisting.
What is the difference between aid vs aide?
It’s easy to see why aid and aide are commonly confused words. Either term describes the concept of assistance, whether it’s helping someone in need or contributing toward a cause. But although they share similar meanings, aid and aide are different words with separate functions in English grammar.
The biggest difference between the two words is that aid is a noun or a verb, while the word aide is only a noun. This might not seem like a big difference in theory, but it’s important to remember how a noun is a person, place, or thing, and a verb is an action word. For example:
- The noun form of aid describes the assistance given.
- The verb form of aid defines the action of providing help.
- The noun aide represents the person that provides help or relief.
Although they’re pronounced the same, the words aide and aid have different spellings, as well. When two or more words have different spellings and definitions but share similar pronunciations, they’re called “homophones.” The Word Counter has covered homophones that are similar to aid vs. aide, such as:
What’s the difference between aid vs. aide as nouns?
While it might be strange, the noun forms of aide and aid reference two separate kinds of “objects,” so-to-speak. The word aid is a helpful inanimate object or the act of assistance, while the word aide is a person who assists others.
The noun aide is short for French “aide-de-camp,” which means “camp adjutant,” or a confidential assisting military officer. In French, the word “aide” also translates to “help” or “assistance,” so perhaps the English language maintained the foreign spelling for people (aide) instead of inanimate objects (aid).
You may notice this subtle difference in common phrases, as well. For example, British English uses the noun aid within phrases like “in aid of” or “what’s this in aid of?” The first phrase replaces the meaning of “this is in support of …” when it comes to charity or financial aid.
“USA Today is donating subscription proceeds in aid of hurricane victims.”
Meanwhile, the phrase, “what’s this in aid of?” is synonymous with the question, “what’s the reasoning behind this?”
The noun aid is also associated with the legal phrase “aid and abet,” which describes the act of assisting and encouraging another to commit a crime.
“Washington Post reports how the owners are guilty of aiding and abetting employees in money laundering.”
Lastly, the most common way to read the word aid is within phrases like “to send aid to …” or “come to the aid of …” English speakers use either phrase to refer to an act that will relieve or save others from an unfavorable situation. In this case, the word aid is similar to the word “rescue” because it is also a noun and a verb.
“FEMA comes to the aid of citizens in times of natural disasters.”
“The New York Times opinion article calls on U.S. political leaders to send aid to furloughed workers.”
Where we see the biggest difference between the nouns aid and aide is within the phrase “a tower of strength.” Cambridge University Dictionary specifically connects the word aide to this phrase, which references a person who provides emotional support and security in times of hardship.
“Whenever I’m sad, my husband acts as a tower of strength.”
The etymology of aid vs. aide
The term aid entered the English Language around the 15h century from the Old French noun ‘aide’ (helper) and the verb ‘aidier’ (to help). Both Old French terms derive from the Latin term ‘adjuvare,’ which consists of ‘ad-’ for “towards” and ‘juvare’ for “to help.” Nowadays, the French verb for “to help” or “to assist” omits the second letter i for ‘aider.’
