I'm looking for some precise and concise ways of saying:
I may or may not have understood you and will confirm by paraphrasing: [...]
"In other words, [...]?" seems to be used often, but I feel like without the question mark it means:
I understood what you said and will prove it by paraphrasing: [...]
I realize the inflection of a statement is often the only thing separating "I think" from "I'm sure," but I'm wondering if there are other options besides "in other words." I say "paraphrasing" but it doesn't necessarily need to imply that I'll definitely be using different words, just needs to imply that I am not positive I understood.
Note: To explain some of the answers below, this was previously titled Echoing to confirm that I understand; however, I edited it as one user pointed out echoing means specifically a word-for-word repetition and that is not necessarily what I'm looking for.
