Intoxicated and given to be overbearing (4-6)
I believe the answer is:
high-handed
'overbearing' is the definition.
(thesaurus)
'intoxicated and given' is the wordplay.
'intoxicated' becomes 'high' (similar in meaning).
'and' says to put letters next to each other.
'given' becomes 'handed' ('hand' can be a synonym of 'give').
'high'+'handed'='HIGH-HANDED'
'to be' is the link.
(Other definitions for high-handed that I've seen before include "Overbearing" , "Domineering, inconsiderate" .)
