What is aaaaa in the English language, please? It happens when you try to say something. Sometimes, we donít know where to start if we want to talk. So, that sound takes place. Thanks.
We would normally write something like "Er" or "Um" to transcribe the sound made when we're thinking.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
