Expert writing Tips
Best practice
Use "which constitutes" to clearly define what something is composed of or equivalent to within a sentence. It helps specify the elements or characteristics that are essential to the subject.
Common error
Avoid using "that constitutes" when "which constitutes" is appropriate. "Which" introduces non-restrictive clauses (additional, non-essential information), while "that" introduces restrictive clauses (essential to the meaning of the sentence). If the clause can be removed without changing the core meaning, use "which".

Ludwig's WRAP-UP
In summary, "which constitutes" is a grammatically sound and frequently used phrase, particularly in formal writing across science, news, and encyclopedic contexts. As Ludwig AI confirms, it functions as a relative clause to provide additional, non-essential information about the composition or nature of something. When writing, remember to use "which constitutes" when the information is non-restrictive and could be removed without changing the core meaning of the sentence, using alternatives like "that comprises" or "that makes up" if a different emphasis is desired. Avoid the common error of using "that constitutes" when "which" is more appropriate to maintain grammatical correctness.
