Interjections are always fun to study! First, what are interjections? Interjections are words or phrases that express emotion, joy, happiness, shock and more! Interjections often stand alone. This means they are not always part of a sentence. Sometimes we add other words like intensifying adverbs to an interjection to add emphasis. Because “What” is also a question word, it is often used to confirm a statement. “Wow” can be used in a positive or negative manner. Proper intonation is very important when using interjections. Just one word in English can be defined many ways with the proper intonation!
