Punctuate the following sentence. please lend me your pencil sir
Please, lend me your pencil, sir.
We have to capitalize the first letter of the sentence. The sentence starts with the word please. So it is a request. So we can use full stop at the end of the sentence. In the given sentence, a comma needs to be placed after Please since it is the introductory phrase. Hence it needs to be set off from the main clause. Similarly, we should place a comma before ‘sir’ to indicate that we are addressing the sir.
