1/ I was wondering how to use the verb "to send" in combination with "hereby or herewith".
When I check the Collins dictionary, I see: "I sent", but when I check via google "I hereby send/sent" I have noticed that "I hereby send" is more used.
Which of those should I use?
Hereby refers to a present action.
I hereby send = I by this means send
Sent is the past tense of send.
I sent you a letter yesterday.
I'm not 100% sure that the following explanation is correct.
I thereby sent = I by that means sent (this may be misleading, I'm not 100% sure that i'm correct).
I'm not a teacher.
