"He is happy, isn't he?"
If you did not use the contraction isn't he, in the question above, would the correct sentence be:
- "He is happy, is he not?"
- "He is happy, is not he?"
Sentence #1 seems to have to have same meaning as the above question but does not become the subject complement of he? Is #2 the grammatical equivalent albeit archaic or uncommon in modern English?
