Suppose I am writing a sentence. The sentence has a sentence in inverted commas. After the closing inverted comma appears, the main sentence also ends. As the main sentence ends, there will a full stop at the end. In this case, there will be three punctuation marks in a row: first, there will be a full stop marking end of quoted sentence; second, there will be a closing inverted comma marking close of the quotation; lastly, there will be a full stop marking end of the main sentence. Take an example: The judgment says "John is guilty.".
To me, this use of full stops is logical; we cannot do away with any of the full stops in the above example.
Am I correct?
