spirit

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

'clutches of booze' is the definition.
'spirit' can be an answer for 'booze' (thesaurus). I'm not certain of the 'clutches of' bit.

'stumbles back with one in the' is the wordplay.
'stumbles' becomes 'trips' ('trip' can be a synonym of 'stumble').
'back' shows that the letters should be reversed in order.
'with one' becomes 'i' (Roman numeral. I am not sure about the 'with' bit.**).
'in the' is an insertion indicator.
'trips' reversed gives 'spirt'.
'spirt' placed around 'i' is 'SPIRIT'.
