Emotional having drunk gin on tap (8)
I believe the answer is:
poignant
'emotional' is the definition.
(thesaurus)
'drunk gin on tap' is the wordplay.
'drunk' indicates an anagram.
'gin'+'on'+'tap'='ginontap'
'ginontap' with letters rearranged gives 'POIGNANT'.
'having' acts as a link.
(Other definitions for poignant that I've seen before include "Arousing sympathy, moving to the feelings" , "Sharply, painfully emotive" , "Touching - gin on tap (anag)" , "Sharply upsetting" , "Evoking sadness or regret" .)
