If you are speaking of "Marion, you are great," yes, that is correct. In English the construction is called "direct address."
No, the sentence "Thank you John" is not grammatically correct. It should be written as "Thank you, John." Adding the comma after "thank you" separates the person's name as an interjection in the sentence.
A sentence splice (alternately, comma splice) is when 2 independent clauses are joined by a comma. This is not grammatically correct. To fix a sentence splice, you can either change the comma to a semicolon, or you can add a coordinating conjunction after the comma (for, and, nor, but, or, yet, so).
Yes, it is grammatically correct; when used, it is followed by a comma. However, it is often overused in writing and shouldn't be used in excess.
No, you need to add a comma after rich. If I were rich, I would buy a mansion.
No. After the word and comma can not be used, as it is grammatically inappropriate to use comma after conjunctions such as and, which are called coordinate conjunctions.
Yes, coordinating conjunctions preceded by commas can be used to correct a comma splice. This involves adding a comma before the coordinating conjunction (e.g., "and," "but," "or") to join two independent clauses properly and create a grammatically correct compound sentence.
Yes, the sentence is grammatically correct. It consists of two independent clauses ("Fred loves to tease Ethel" and "Lucy loves to tease Desi") joined by the coordinating conjunction "and."
no
The grammatically correct way to phrase this too-vague question is, "Can you give me more sentences with the words, already?" Note the pluralization of "sentence" and the additional comma.
Yes, using a comma before "because" is correct when you are providing an explanation or reason for the previous statement in a sentence. This structure helps to connect the two parts of the sentence more effectively. Example: "I decided to stay home, because I wasn't feeling well."
If talking about a Co as in a Company, a period will suffice.
