Hereof is another stiff document word. It means “of this” — belonging to this paper, or about this paper. “On the date hereof” means on the date of this document. “The parties hereof” means the people this document is about. English built it as here + of, and it has been in the language a long time.

Hereof hereof is another另一個 stiff document word生硬的公文用語。It means意思是 "of this"「of this」（這個的）, belonging to this paper, or about this paper也就是屬於這份文件、或跟這份文件有關. "On the date hereof"「On the date hereof」 means on the date of this document意思是在這份文件的日期. "The parties hereof"「The parties hereof」 means the people this document is about意思是這份文件所談到的人。English built it as英文是用 here + ofhere加of組成這個字, and it has been in the language a long time而且用了很久了。

Though actually, it is easy to mix up with its neighbours. Herein is in this document (the contents sitting inside it). Hereof is of this document (belonging to it, about it). Hereto is to this document (often “attached hereto,” meaning stuck onto it). The little words in, of, and to are doing different jobs; the here is the same “this official paper” each time.

Though actually不過, it is easy to mix up with its neighbours它很容易跟旁邊長得像的詞搞混。Herein herein is是 in this document「在這份文件裡」 (the contents sitting inside it)（指裡面的內容）。Hereof hereof is是 of this document「屬於這份文件」 (belonging to it, about it)（也就是跟它有關）。Hereto hereto is是 to this document「附於這份文件」 (often常說 "attached hereto,""attached hereto" meaning stuck onto it意思是黏附在上面)。The little words in, of, and toin、of、to這三個小字 are doing different jobs做的是不同的工作; the herehere is the same每次指的都是同一份 "this official paper"「這份正式文件」 each time。

You will not hear hereof in a café. It lives in contracts, deeds, and formal letters.

In a café在咖啡廳裡 you will not hear你不會聽到 hereofhereof這個字。It lives常出現 in contracts, deeds, and formal letters在合約、契據和正式書信裡。
