If I can't understand what someone said very well, how to ask him to repeat his words, but in slightly different way?
If I say,
I don't understand, he may think that I'm not agree with his opinion.
I'm not sure if
Sorry? work in written English.
If what he said looks very simple: there is no uncommon words, then, I am expected to understand, however I can't. So it's more likely that I'm against their opinions if I say I don't understand. Because what he said is so easy. So, I would like him to repeat his sentence in a different way, using different words maybe. How can I ask him to repeat in different way politely?
