To understand feels good. Not being able to understand feels bad. And, being able to express you don’t understand is super important.
Having a variety of expressions is also helpful. Too often, non-native speakers will jump straight to “I don’t understand”. Depending on the context, straight and to the point can be best. Unfortunately, if you’re always too direct and basic, it makes your language comprehension skills seem lower than they are.
If you’re in the intermediate-advanced range, you should know different ways to dance around your unfamiliarity:
- I tried, but I still don’t get it.
- I’m not sure I follow.
- I think I might, but I’m not positive on what you mean.
Those kinds of phrases, while natural, are a bit harder to utilize.
It might be easier to use a substitute like “to wrap my head around” (to comprehend, to visualize, to understand fully/well).
Most of the time, you’ll use this phrase in the negative form:
- I hear you, but that’s so hard for me to wrap my head around.
- I can’t quite wrap my head around it.
