Drinking again, the ordinary failing (11)

I believe the answer is:

rehydration

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

'drinking again the ordinary failing' is the definition.
I can't tell whether this definition defines the answer.

'the ordinary failing' is the wordplay.
'failing' is an anagram indicator (a failed spelling of the word).
'the'+'ordinary'='theordinary'
'theordinary' anagrammed gives 'REHYDRATION'.

Can you help me to learn more?

I've seen this clue in The Times.
