I got what you mean.

I understood what you meant.

I understand what you meant.

I get your point.

I didn't understand what you said.

I understood everything that you said to me.

I figured it out.

Got it!

I got it.

I get the idea.

I understood.

Am I understood?

I didn't understand.

Now I understand.

Now I get it.

I misunderstood.

I misunderstood.

I understood that.

Now I get it, I understand why people would want to focus on English.

I think I understand.

I think I've got it.

I understood almost everything.

I haven't got it yet.

I don't really get the point.

Thank you, I understand everything.

I understood very well.

I didn't understand a thing.

I didn't understand anything.

I never understood that.

I didn't get them.

I didn't get them.

I never understood this.

I still don't understand it.

And I finally worked it all out.

I didn't understand the meaning.

I didn't get the meaning.

I didn't understand this joke.

I didn't get any of that.

I see I was wrong.

I, too, didn't understand anything.

I didn't understand anything, either.

I didn't understand the joke.

I understood almost nothing.

I hardly understood anything at all.

I think I finally understand now.
