How do you use thereto?

The Word "thereto" is used to refer to something that has been previously mentioned or is relevant to a specific context. It often appears in legal or formal writing to denote a connection or relationship to an earlier statement or document. For example, one might say, "The parties agreed to the terms outlined in the contract and affirmed their commitment thereto." In this case, "thereto" refers back to the "terms outlined in the contract."
