An vs And: What's the Difference?

The words an and and are often confused because of their similar spelling. In this article, we explain the difference between them.

An is a determiner that means "the indefinite article before nouns with a vowel sound".

And is a conjunction that means "expressing two elements to be taken together or besides each other".

The Difference Between An vs And

Let's take a closer look at each word.

An is an indefinite article. It comes before a noun and it's used when you aren't referring to one specific noun.

An has the same meaning as a, but an precedes nouns that start with a vowel sound. (It's important to note that the sound of the noun is more important than the spelling. For instance, we would say an hour because hour sounds like it starts with an o.)

Examples of An in Sentences

• He took an apple from his pocket.
• It was an ordeal, but we finally made it.
• They knew it had been an honest mistake.

And is a conjunction. It can connect words that are the same part of speech, such as two adjectives (e.g. calm and steady) or two nouns (e.g. eggs and bacon). And can also connect independent and dependent clauses. You can even start a sentence with and if the new sentence is connected to the previous one.
