Got us to display zest (5)
I believe the answer is:
gusto
'zest' is the definition.
(synonyms)
'got us to display' is the wordplay.
'to display' indicates anagramming the letters (I've seen 'displaying' mean this (the anagrammed letters display the answer)).
'got'+'us'='gotus'
'gotus' is an anagram of 'GUSTO'.
(Other definitions for gusto that I've seen before include "Vigorous and enthusiastic enjoyment" , "Great relish" , "Great enthusiasm" , "Zest, exuberance" , "Zest, zeal" .)
