"Thereto" means "to that" — to the agreement, document, or thing just mentioned. It lives almost entirely in legal writing, and mostly in a few set phrases.

"Thereto"「thereto」 means意思是 "to that"「對那個」 to the agreement, document, or thing just mentioned指前面剛提到的那份協議、文件、或東西。It lives almost entirely它幾乎只出現 in legal writing在法律文件裡 and而且大多用在幾個固定片語裡 mostly in a few set phrases。

The commonest by far is "the parties thereto" (the people who signed that agreement) and "attached thereto" / "annexed thereto" (attached to that document): "the contract and the schedules attached thereto". Another set phrase is "pursuant thereto", meaning "following that agreement".

The commonest by far目前最常見的是 "the parties thereto"「the parties thereto」（簽了那份協議的當事人） and和 "attached thereto" / "annexed thereto"「attached thereto」／「annexed thereto」（附在那份文件上） : "the contract and the schedules attached thereto"「合約以及附在其上的附表」。Another set phrase另一個固定片語是 "pursuant thereto"「pursuant thereto」 meaning意思是 "following that agreement"「依據那份協議」。

Like "thereof", it comes after the word it attaches to, and its purpose is to point back without repeating a long title. In ordinary English you say "to it" or "to that".

Like "thereof"跟「thereof」一樣 it comes after它接在 the word it attaches to它所指的那個字之後 and而 its purpose is它的作用是 to point back指回前面 without repeating a long title而不用把落落長的名稱再講一次。In ordinary English一般英文裡 you say你會說 "to it" or "to that"「to it」或「to that」。

Notice the pair: a contract you are writing says "the parties hereto" (to THIS contract); a contract talking about a different one says "the parties thereto". That here/there switch is the heart of all these words.

Notice the pair注意這一組對照 a contract you are writing你正在寫的合約 says會說 "the parties hereto"「the parties hereto」（指這份合約） a contract talking about a different one談到另一份合約時 says則會說 "the parties thereto"「the parties thereto」。That here/there switch這個here／there的切換 is the heart of all these words就是這一整組字的關鍵所在。
