The word 'thereof' is used when referring to something that was just mentioned. It is often used in legal documents, contracts, and formal writing. For example, if you were writing a contract for a house sale, you may state "The buyer shall pay the full purchase price to the seller and shall provide proof thereof." In this sentence, 'thereof' refers to proof of the full purchase price. Essentially, 'thereof' can be used to avoid repeating information that has already been stated.
