aargh

I'm a little stuck... Click here to teach me more about this clue!

'it's awful half' is the definition.
I can't tell whether this defines the answer.

'content of charity sale going to grand hotel' is the wordplay.
I cannot really understand how this works, but
'content' could be 'aa' (AA is an example) and 'aa' is found in the answer.
'grand' could be 'g' (G is short for grand as in a thousand) and 'g' is present in the answer.
'hotel' could be 'h' (phonetic alphabet: alpha, bravo, charlie etc.) and 'h' is found in the answer.
A single letter 'r' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...

'the' is the link.
