Expert writing Tips

Best practice

When using "which were effective", ensure the context clearly defines what constitutes 'effectiveness' and what specific results were achieved. This adds clarity and strengthens the statement.

Common error

Avoid using "which were effective" when "that were effective" is more appropriate. Use 'that' for restrictive clauses (essential to the sentence's meaning) and 'which' for non-restrictive clauses (added information). For example, "The strategies that were effective focused on customer retention" (essential) vs. "The strategies, which were effective, led to increased revenue" (added information).

Linguistic Context

The phrase "which were effective" functions as a relative clause, providing additional, non-essential information about a noun or noun phrase. As Ludwig AI confirms, this phrase typically modifies a preceding element, adding descriptive detail regarding its effectiveness. For example, 'the strategies, which were effective,...'.
