Commonly Confused Words
that / which
Use that in restricting (limiting) clauses that provide essential, identifying information: "The rocking chair that creaks is on the porch." You are singling out the chair from two or more chairs. Use which in nonrestrictive clauses -- clauses that provide non-essential, parenthetical information: "The rocking chair, which creaks, is on the porch." You have one rocking chair, and it creaks. If you are unsure whether a clause is restrictive or not, try omitting it. Omitting a restrictive clause will change the core meaning of your sentence. Note: A non-restrictive which clause has commas around it; a restrictive that clause has none.
