Being diverted made us excited (6)
I believe the answer is:
amused
'being diverted' is the definition.
(synonyms)
'made us excited' is the wordplay.
'excited' is an anagram indicator.
'made'+'us'='madeus'
'madeus' is an anagram of 'AMUSED'.
(Other definitions for amused that I've seen before include "Mildly entertained by Medusa" , "Victoria reputedly wasn't" , "Delighted" , "Mildly diverted or entertained" , "Made (someone) laugh" .)
