I'm bringing this question because I'm not sure whether a preposition in the end of a sentence can be moved to the middle, especially considering prepositional verbs.
Also, I'd like to know which grammar section covers prepositional verbs in a wide approach. Please, could you give me some guidance about it?
- As a start, we would like to know more details about the project that you are engaged in.
This sentence sounds ok for me.
- As a start, we would like to know more details about the project that you are engaged.
This one sounds incomplete.
- As a start, we would like to know more details about the project in which you are engaged.
I'd say that it's correct, but every time I got myself in this situation of thinking something sounds good in my mother tongue, I need to ensure whether it's correct in English.
Thank you for your attention! :-)
