Regarding upper leg of Iron Maiden, it's said (7)
I believe the answer is:
femoral
'regarding upper leg of iron maiden it's said' is the definition.
I can't judge whether this definition defines the answer.
'iron maiden it's said' is the wordplay.
'iron' becomes 'Fe' (Fe is the chemical symbol for iron).
'maiden' becomes 'm' (cricket abbreviation).
'it's said' becomes 'oral' (I've seen this before).
'fe'+'m'+'oral'='FEMORAL'
Can you help me to learn more?
(Other definitions for femoral that I've seen before include "Of the thigh artery" , "Relating to the thigh bone" , "Of or near the thighbone" , "Lor, fame can relate to the thigh" .)
