Exclamatives are a type of sentence that express strong emotions or reactions, such as surprise, joy, or admiration. They often begin with words like "what" or "how," and they convey a sense of intensity. For example, "What a beautiful day!" or "How amazing that performance was!" These sentences are not just statements; they emphasize feelings and reactions. In English, exclamatives can be formed using various structures, but they typically end with an exclamation mark to highlight their emotional tone. They are commonly used in everyday conversation and writing to convey enthusiasm or astonishment about a particular event, object, or experience.
