Expert writing Tips
Best practice
When using "which will probably", ensure the clause it introduces is nonrestrictive and adds extra information to the sentence, rather than being essential to its meaning. Use commas to set off the clause.
Common error
Avoid using "that" instead of "which" when introducing a nonrestrictive clause. "That" is typically used for restrictive clauses that are essential to the sentence's meaning. For example, prefer "The decision, which will probably be unpopular, was necessary" over "The decision that will probably be unpopular was necessary."
