Best practice
Reconsider using the phrase "which well" in formal writing. It is often grammatically awkward and can be replaced with clearer alternatives like "which is effective" or by rephrasing the sentence to avoid the construction altogether. Always ensure clarity and precision in your writing.

A frequent error is using "which well" when intending to describe the quality or effectiveness of something. Avoid this by ensuring the relative pronoun "which" correctly introduces a clause that modifies a noun, and "well" appropriately functions as an adverb or adjective within that clause.

FAQs
How can I use "which" correctly in a sentence?
Use "which" to introduce a nonrestrictive clause, providing extra information about a noun that isn't essential to its meaning. For example, "My car, "which is old", still runs well."
What are some alternatives to using "well" as an adverb?
Instead of "well", consider using adverbs such as "effectively", "adequately", or "successfully" to describe how something is done. The best choice will depend on the specific context.
Is "that well" a better phrase than "which well"?
While "which well" is generally grammatically incorrect, "that well" can be used to refer to a specific well. However, it's crucial to ensure the context makes the reference clear and unambiguous.
How can I rephrase a sentence to avoid using "which well"?
Try restructuring the sentence to clearly state the intended meaning. For example, instead of "a method "which well" describes the process", say "a method that effectively describes the process" or "a method that provides a good description of the process."
