hello.^^ can i ask you a question (?).. is this sentence right? "they no coming to the party this evening."? pls help and thank you :)

Hi, thank you for asking me your question. Unfortunately your sentence "they no coming to the party this evening" does not comply fully with the rules of Standard Written English, one reason being that as a complete sentence it should begin with a capital letter, i.e., the "t" of "they" should be upper case "T."
But a much more important reason that your sentence is not "correct" or "grammatical" is it does not follow the rules for negating a declarative (or "normal" or "unmarked") sentence in English, which are notoriously complicated and unusual for non-native speakers to learn. Specifically, unlike many other languages we generally cannot negate a declarative sentence simply by adding a negative particle like "no" directly before the verb as your sentence does, but instead before adding "not," the negative particle we in fact use for sentence negation, we usually must introduce a form of "do"--and transfer to it the appropriate tense from the main verb of the declarative sentence--and then put "not" between the new auxiliary verb "do" and the main verb (as we do with other auxiliaries in English, e.g., "They should not come" and "They will not come"). Thus, the "correct" negation of "They come" is "They do not come," or more informally "They don't come."
A secondary grammatical issue is that in your original sentence you have as the main verb the present participle "coming," but in English this does not count as a "conjugated" or "finite" verb, meaning that it requires an auxiliary, in this case a form of "be" to form what is known as the present progressive (or "present continuous") aspect. In other words, the correct affirmative version of your sentence would begin "They are coming . . ." and especially in the spoken language either "are" or "not" is contracted with another element of the sentence, hence in the negative version one would be most likely to hear either "They're not coming" or "They aren't coming" instead of "They are not coming," though the last is perfectly acceptable, if not preferred, in written English.

The answer hasn’t got any rewards yet.
