In our book under 改錯句 there is the following exercise:
外邊很冷,快把大衣穿穿!
I assume they consider it wrong because the object is not definite. Is that so, or is there any other reason?
If the context makes it clear that we are talking about a specific 大衣,would the sentence be ok, or do I absolutely need to grammatically express the definite nature by
那件大衣/你的大衣/爸爸送給你的大衣⋯?
Edit:
according to our book, reduplication of the verb makes the predicate complex, fulfilling the requirement for 把字句。 The example given is: 把桌子擦擦。
