Consider the simple question
Are you trying to tell me, …?
and its short answer
What is the correct way to emphasise this answer with an adverb, like
I am precisely. or I precisely am.
Both possibilities sound equally weird to me. The first sentence seems incomplete to me, instead
I am precisely trying to.
would sound more correct but loses its terseness. The second sentence feels a bit odd but follows the same pattern as “I certainly will.” which is definitely a correct answer to a question “Are you going to …”.
I hope someone can shed some light here!
