Restrictive ElementA word, phrase, or clause that is essential to the meaning of the noun or pronoun it modifies.

Key Rules & Conventions
Punctuation for Restrictive Elements
Do NOT use commas to set off restrictive elements.
If the information is essential to identify or specify the noun it modifies, it should directly follow the noun without any commas. Commas would incorrectly suggest the information is extra.
Punctuation for Nonrestrictive Elements

If the information is non-essential and merely adds extra detail, it must be enclosed by commas (if in the middle of a sentence) or preceded by a comma (if at the end). These commas act like parentheses, signaling 'by the way' information.
Choosing 'That' vs. 'Which' (General Guideline)
Use 'that' for restrictive clauses and 'which' for nonrestrictive clauses....

Challenging
Analyze the sentence: "The final chapter of the book, which I found very confusing, resolves the main conflict." Why is the punctuation of the clause "which I found very confusing" correct?
A.It is correct because the clause is restrictive, specifying which chapter resolves the conflict.
B.It is correct because "The final chapter of the book" is a specific, unique item, making any following descriptive clause non-essential.
C.It is incorrect; the commas should be removed because the information is essential.
D.It is incorrect; "which" should be changed to "that" to indicate it is non-essential.
