Is heel turned to show bones in foot? (5)
I believe the answer is:
tarsi
'bones in foot?' is the definition.
'tarsi' can be an answer for 'bones' (bones of the foot). I'm unsure of the 'in foot?' bit.
'is heel turned' is the wordplay.
'heel' becomes 'rat' (I can't explain this - if you can you should believe this answer much more).
'turned' says the letters should be written backwards.
'is'+'rat'='israt'
'israt' back-to-front is 'TARSI'.
'to show' is the link.
Can you help me to learn more?
(Other definitions for tarsi that I've seen before include "parts of leg" , "Ankle bones" , "Bones of the ankles and heels" , "Parts of skeleton" , "collections of bones?" .)
