Expert writing Tips

Best practice

When using "which were necessary", ensure the context clearly establishes why those actions or items were indeed essential. The surrounding sentences should provide sufficient justification.

Common error

Avoid overusing "which" clauses, as they can sometimes make sentences wordy. Consider whether you can rephrase the sentence for better clarity and conciseness. For example, instead of "the changes, which were necessary, were implemented", try "the necessary changes were implemented".

Linguistic Context

The phrase "which were necessary" functions as a relative clause, providing additional information about a noun or noun phrase. As Ludwig AI points out, it indicates actions, items, or conditions that were essential or required in a specific context. The relative pronoun "which" introduces the clause, and the verb "were" links it to the adjective "necessary".
