Expert writing Tips
Best practice
Use "which is already" to provide additional, non-essential information about a noun. The sentence should still make sense if the "which is already" clause is removed.
Common error
Avoid using "that" instead of "which" when introducing non-restrictive clauses. "Which" is used for clauses that add extra information but are not essential to the sentence's meaning. If the clause is essential, use "that".

Use "which is already" to add extra, non-essential information about a noun in your sentence. For example, "The project, "which is already" behind schedule, needs more funding."
What's the difference between "which is already" and "that is already"?
"Which" introduces a non-restrictive clause, adding extra information, while "that" introduces a restrictive clause, essential to the sentence's meaning. "The book, "which is already" a bestseller, is being adapted into a movie" vs "The book that is already selling well will be reprinted."

Alternatives to "which is already" include "that is in progress", "that is currently in place", or "that is present", depending on the specific context.
Is it always necessary to use "which is already"?
No, it's not always necessary. "Which is already" is useful for adding context or detail, but if the information is not crucial, the sentence may be clearer without it.
