Just about any word in English can be used as an interjection. Interjections are used to show emotion or feelings! “Ouch” is used to express sudden pain. This can be physical or emotional. “Bravo” is used to praise or congratulate someone. Remember that all sentences must have at least one verb. Interjections stand alone as one word or phrase. Most interjections are placed at the beginning of a statement followed be a comma or exclamation point. “Ouch and Bravo” are often placed at the end of a statement to provide more emphasis.
