Is it true that If you punctuate a fragment like sentence are still left with fragment?

That's a very interesting observation! You're right, adding punctuation alone doesn't magically transform a sentence fragment into a complete sentence.

Here's why:

* Sentence Fragments Lack Essential Elements: A sentence fragment is missing a subject, a verb, or both. Punctuation just helps organize the words, it doesn't add the missing parts.

* Example: "Running down the street." This is a fragment because it lacks a subject (who is running?). Adding a period ("Running down the street.") or an exclamation point ("Running down the street!") doesn't change the fact that it's missing a subject.

To fix a fragment, you need to add the missing parts:

* "The dog was running down the street." Now we have a subject (the dog) and a verb (was running), making it a complete sentence.

Think of it like this: Punctuation is like the furniture in a house. You can arrange it beautifully, but without walls, a roof, and doors, it's not a complete house. The missing parts of a fragment are like the missing walls, roof, and doors.
