Being diverted made us excited (6)
I believe the answer is:
amused
'being diverted' is the definition.
('amused' can be a synonym of 'diverted')
'made us excited' is the wordplay.
'excited' indicates anagramming the letters.
'made'+'us'='madeus'
'madeus' with letters rearranged gives '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" .)
