The sentences that contain examples of contested usage are:
-
The postman needs to know who this letter is addressed to so it can be delivered.
- The phrase "who this letter is addressed to" is often debated because 'to' should not be used at the end of the sentence in formal English.
-
Stephanie started reading the book first, and therefore she finished it before I did.
- The use of "therefore" in this context is sometimes contested; many argue it should be used in a more logical structure, which leads to discussions about its proper placement and use.
In contexts of contested usage, there may be alternative or traditional views regarding syntax or word choice that can be worth noting.
