Decked fellow singer, apparently in the middle of act (9)
I believe the answer is:
decorated
'decked' is the definition.
Both the definition and answer are adjectives. Maybe you can see an association between them that I don't see?
'fellow singer apparently in the middle of act' is the wordplay.
I cannot really understand how this works, but
'fellow' could be 'ted' (I've seen this in other clues) and 'ted' is found in the answer.
'of' could be 'o' and 'o' is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for decorated that I've seen before include "Embellished" , "Awarded medal(s)" , "Gothic style following 6 8" , "Ornate" , "like a warrior?" .)
