I didn't understand a word you just said/ of what you just said/ that you just...

Hi everyone,

Which one of the following sentences is acceptable?

  • I didn’t understand a word you just said.
  • I didn’t understand a word of what you just said.
  • I didn’t understand a word that you just said.

Thanks
Alexandro.

All of them.
‘I don’t understand…’ is also possible.

Thanks Beeesneees, but I wonder, doesn’t it sometimes get boring to read: ‘Thanks Beeesneees’? You know I’m always happy and thankful when you answer my threads.
Alexandro.
