how to understand the punctuation mark

Punctuation marks are symbols used in writing to make the meaning of sentences clear. They are like the traffic signs that tell us when to stop or go. For example, a period (.) tells us that a sentence has ended. A comma (,) tells us to pause. A question mark (?) tells us to ask a question. An analogy is like this: Punctuation marks are like the musical notes that tell a musician how to play a song. Each punctuation mark has a different sound and meaning. A fun fact about punctuation is that the exclamation mark (!) was first used in the 16th century. It was originally called the “note of admiration” or “note of joy”.
