What is the correct formation of grammar in the sentence What are you going to draw?
What are you going to draw?
It is correct.
It depends on the structure of the entire sentence. For example, "Bill, Bob, and I are going to the grocery store" is correct grammar in that sentence, but "Sandra is going to meet Bill, Bob, and me" is also grammatically correct because of the structure of its sentence. It really all depends upon the context in which the phrase "Bill, Bob, and I" are being put into. == ==
Traditional grammar is correct "textbook" grammar. Functional grammar is colloquial grammar, grammar that people use in regular conversation. For instance, people tend to say "Who are you going with?" even though that is incorrect and the correct form would be "With whom are you going?" (prepositions should always precede their objects, and "who" should be in the objective case "whom").
