An interjection is a word or phrase that expresses strong emotion or sudden feeling. It often stands alone and can convey excitement, surprise, joy, or even frustration. Common examples include words like “Wow!”, “Oh no!”, and “Yay!” Interjections add color to our speech and writing, making it more expressive and engaging. These words are usually followed by an exclamation mark when the emotion is strong, such as in “Hooray!” or “Ouch!” when someone feels pain. Interjections can also be used in a more subdued way, like “Well,” or “Hmm,” to indicate thoughtfulness. They help convey the speaker's feelings about a situation or event.
