An exclamation mark is a punctuation symbol used to express strong emotions, excitement, or emphasis in writing. It looks like a vertical line with a dot underneath it: “!”. Writers often use it to convey feelings such as surprise, joy, or anger, making their sentences more impactful. In English grammar, the exclamation mark typically appears at the end of a sentence. For example, in the sentence “Watch out!” the exclamation mark highlights the urgency of the message. It is important to use exclamation marks sparingly to maintain their effectiveness and avoid overwhelming the reader.
