Many people confuse these two concepts, thinking they are one and the same. But in fact, there are some key distinctions between them. The Main differences between grammar and punctuation is explained below:
Grammar
Grammar is the way we put words together to form sentences and paragraphs. It is the fundamental structure of language that describes what words should go where and why.
One of the most basic grammar rules is that every sentence needs a noun and a verb. If there is no noun or verb, or both, it is not a sentence. It is just a jumble of words and it is difficult to understand what it means. However, when you put a noun and verb together, it creates meaning.
Tiny two-word sentences like these are examples of grammar at work. From there, grammar describes all the ways we can add words so that each one makes sense and brings clarity.
Punctuation
Punctuation is the symbols we use in writing to make it easier to read. They help us understand when to pause, how words are related, and how the writer is feeling.
A period (.) brings a sentence to a full stop.
A comma (,) is a small pause in the middle of sentences. It can divide content by clause, or delineate list items from one another.
A question mark (?) goes with a question. It's very self explanatory.
A semicolon (;) joins two related independent clauses in place of a comma and a coordinating conjunction (and, but, or, nor, for, so, yet). Make sure that when you use the semicolon that the connection between the two independent clauses is clear without the coordinating conjunction.
