Expert writing Tips

Best practice

Use "which occur" to introduce nonrestrictive clauses that provide additional information about a noun or event, ensuring the clause is set off with commas.

Common error

Avoid using "which occur" in restrictive clauses (those essential to the sentence's meaning). In such cases, "that occur" is generally preferred. Use "which occur" only for nonrestrictive clauses, which add extra information and are set off by commas.

Ludwig's WRAP-UP

In summary, the phrase "which occur" serves as a relative clause introducer, adding descriptive details about preceding nouns or events. While grammatically sound, according to Ludwig, it's essential to distinguish its use in nonrestrictive clauses from the use of "that" in restrictive clauses. Alternatives like "that happen" may be suitable for less formal contexts. Due to the lack of specific examples in the provided data, assessing its frequency and typical usage patterns is challenging, but Ludwig's AI confirms its grammatical correctness and usability.

FAQs

How do I use "which occur" in a sentence?

Use "which occur" to introduce a nonrestrictive clause that provides additional information about something already mentioned. For example, "The weather patterns, "which occur" frequently in this region, can be unpredictable."

Is "which occurs" or "that occurs" better?

"Which happen" and "which occur" are largely interchangeable, with "which occur" being slightly more formal. Consider using "which happen" in casual contexts and "which occur" in more formal writing.
