C. Three or more of any parallel structures, including independent clauses, are separated by commas and one coordinating conjunction before the last item:
1. xxxx, yyyy, cc zzzz
2. wwww, xxxx, yyyy, cc zzzz
3. vvvv, wwww, xxxx, yyyy, cc zzzz
4. uuuu, vvvv, wwww, xxxx, yyyy, cc zzzz
Note that, when there are three or more parallel structures, a coordinating conjunction (cc) comes before the last item. Also, note that the final comma (the one before the conjunction) is optional. The parallel structures can be anything: nouns, verbs, adjectives, adverbs, prepositional phrases, subjects, predicates, subordinate clauses, independent clauses,...
Here are some examples of C.1. above (3 parallel structures):
He sings, she dances, and everybody claps. (independent clauses)
He won the lottery, quit his job, and bought presents for all his friends. (predicates)
He bought a car, a motorcycle, and a computer. (nouns)
The motorcycle is red, white, and blue. (adjectives)
Everybody wants to meet him, to talk to him, and to get some money from him. (infinitive phrases)
"Garden path sentences" such as "The woman whistling tunes pianos" are grammatically correct but require reinterpretation by the end, and are used in psycholinguistics to show that people build their understanding of a sentence one word at a time
The three parallel elements in this structure are predicates such as
1. are grammatically correct, 2. require reinterpretation, and 3. are used. Therefore, we need to use the comma.
If we do not use the comma before the last and, this choice must be wrong. If so, what is the correct choice for this question?
Thank you
daagh Sir for the wonderful article and your explanation.
I actually thought over the issue before questioning the supposedly correct choice:
If we consider that there are three elements, we must use a comma before the second element as well.
Correct: Sentences
are correct
, but
require, and
are used.
The 3 verbs refer to the same subject correctly.
However absence of a comma before the second element (
but require) implies that we have just 2 elements, not 3:
first element: are correct but require
second element: are used
If these two elements refer to the same subject (
sentences), we should not have the comma. However introducing a comma before
are used (and not having a comma before
but require) implies that the second element (
are used) should have its own subject - isn't it?
Moreover as I understand, using comma before
and (in case there are 3 or more elements) is optional, whereas using comma before
and (in case there are 2 verbs referring to the same subject) would be wrong.
Kindly correct me if I am wrong.
