A bit drunk from gratuities given to youth leader (5)
I believe the answer is:
tipsy
'a bit drunk' is the definition.
(I've seen this before)
'gratuities given to youth leader' is the wordplay.
'gratuities' becomes 'tips' ('tip' can be a synonym of 'gratuity').
'given to' says to put letters next to each other.
'youth leader' becomes 'y' (I've seen this in other clues).
'tips'+'y'='TIPSY'
'from' acts as a link.
(Other definitions for tipsy that I've seen before include "affected by drink" , "1 over 8" , "Woozy" , "Merry, squiffy" , "Inebriated" .)
