Interjections are a part of speech that are exclamations. They usually come at the beginning of a sentence, and they are used to show strong emotion, surprise, or excitement. Interjections are not related to any other words in the sentence. They just serve to show emotion or to introduce the sentence.
Even though they are one word or a short phrase, strong interjections are often followed by an exclamation point. Interjections that do not show such strong emotion are still set apart from the sentence with a comma.
Some interjections do not express very strong emotion, and they are used to introduce the sentence. They are introductory words. They are still classified as interjections because they are not related to any other words in the sentence.
