Bony frame of piano used by singer (6)
I believe the answer is:
pelvis
'bony frame' is the definition.
(I've seen this before)
'piano used by singer' is the wordplay.
I cannot quite understand how this works, but
'piano' could be 'p' (musical abbreviation) and 'p' is present in the answer.
'singer' could be 'elvis' (I've seen this before) and 'elvis' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Other definitions for pelvis that I've seen before include "Hip structure" , "Large bony frame" , "Basin-shaped framework of bones at lower end of body" , "Large bone" , "Section between torso and legs" .)
