How to Express Lack of Understanding
The first step is to tell the person that you are not sure that you have understood them fully. Let’s look at a few useful phrases:
Example: I’m sorry but I’m not sure (that) I understand.
Example: Sorry, I’m not sure (that) I know what you mean.
Example: Sorry, but I don’t quite follow you.
Using the word “that” in two of the phrases is more suited for formal written communication, such as work-related emails.
Other times, you may understand part of what someone has said but need clarity (ясность) on another part. In such situations, you can be more exact. Here are some examples:
Example: I’m sorry but I’m not sure I understand what you mean by “tech giants.”
Example: Sorry, but I don’t quite follow what you’re saying about the new policy.
