Expert writing Tips
Best practice
When using "which were sent", ensure that "which" refers clearly to the noun you intend. Ambiguity can confuse the reader and weaken your writing.
Common error
Avoid using "that" instead of "which" in non-restrictive clauses. "Which" introduces additional, non-essential information, while "that" is used for essential information. For example, "The letters, which were sent last week, arrived today" (correct) versus "The letters that were sent last week arrived today" (incorrect, unless specifying a subset of letters).
