I'm currently writing a paper about a syntactic issue in English and I was curious how these sounded to everyone.
- Sam put carefully the coffee on the desk.
- Sam put the coffee carefully on the desk.
- Sam carefully put the coffee on the desk.
- Sam put the coffee on the desk carefully.
My opinion is that (1) sounds completely ungrammatical, (2) sounds awkward but is grammatical, and that (3) and (4) are both equally grammatical and not awkward at all.
Is the ability to interject adverbs between the direct and indirect objects like in (2) a common thing that happens?
