Obedient one of Greek legend my awful Nimrod (8)
I believe the answer is:
myrmidon
'obedient one of greek legend' is the definition.
I can't tell whether this defines the answer.
'my awful nimrod' is the wordplay.
'awful' indicates anagramming the letters.
'nimrod' with letters rearranged gives 'rmidon'.
'my'+'rmidon'='MYRMIDON'
Can you help me to learn more?
(Other definitions for myrmidon that I've seen before include "Unquestioning follower" , "keen backer-up" , "Henchman" , "Faithful follower, after the Greek soldiers loyal to Achilles" , "I'll do as the captain says" .)
