I feel very confused at this question. It may be split into 2 questions. A. Must a transitive verb always be follow by an object? B. If NO is the answer to Q A. , then under what circumstances the object can be omitted?
The example is, Wait a moment, I am going to correct it and update it. I doubt if it can be rephrased as "Wait a moment, I am going to correct and update it. See I am in a dilemma; I believe an object must go after am transitive verb so I think the second one is wrong; I try to find a simpler way to express and the second one sounds all right to me and I feel like it.
In short, I want to know whether it is grammatically correct to say "Wait a moment, I am going to correct and update it." I think the object of "it" has been omitted after "correct". Longman dictionary says both verbs of "correct" and "update" are transitive.
