Best practice
When using "which I thought", ensure the clause it introduces logically connects to the main sentence, providing relevant context or explanation.
Common error
Avoid replacing "which" with "that" when the clause is nonrestrictive and adds extra information, as this can alter the meaning or sound unnatural. "Which", preceded by a comma, is typically used for nonrestrictive clauses.
