Being annoyed, rode us ragged! (6)
I believe the answer is:
roused
'ragged' is the definition.
Although both the answer and definition are past participle verbs, I don't see how they can define each other.
'being annoyed rode us' is the wordplay.
'being annoyed' indicates anagramming the letters.
'rode'+'us'='rodeus'
'rodeus' is an anagram of 'ROUSED'.
Can you help me to learn more?
(Other definitions for roused that I've seen before include "Made to waken or to become excited" , "Galvanized" , "Soured (anag.)" , "Stimulated" , "Woken up or moved to action" .)
