Wrong send or wrong sent?

Both are actually incorrect. Send and sent are verbs. Thus, I say "wrong sending." Here, wrong is used as an adjective to describe the noun (sending).

It is incorrect to say "wrong sent" basically because sent is a verb and it is an adverb, not an adjective that modifies a verb. The correct form therefore is wrongLY sent.

I also use missent.

"Na-received" is also redundant for me. I just use "na-receive" or simply received.

Wrong Sent

I agree with what Jack said. Don`t expect text messaging to be grammatically correct. Technology is deteriorating our English proficiency.

Anyway, to answer your question, I think the best way to say it is, "I sent you a wrong message." Something like that. Haha.

However, if you are trying to find out what the noun form of such occurrence is, "wrong send" is widely accepted. Not that it`s grammatically correct, I must say.

By the way, "na-received" is redundant. It shouldn't be Tagalized, even. Just put it simply as "received."

I agree with Kahlan. Both are grammatically wrong, erroneously, which is a mistake! So, for the second time once more, with feeling, I would like again to reiterate what I have previously stated before, that ....

Grammatically correct in text messaging is not to be expected. If you want to write an award winning thesis you don't do it on a keypad with numbers on it. Your message will be way too long and boring. Nobody will want to txt you. Speed is more critical than accuracy.

missend or missent!

wrong send or wrong sent is totally wrong!

those are everyday words most filipinos use. not sure if they are grammatically correct but if we understand one another why bother about form.

i usually use missent. better than saying those two phrases.
