Part of foot used for spinet (6)
I believe the answer is:
instep
'part of foot' is the definition.
(I've seen this before)
'for spinet' is the wordplay.
'spinet' anagrams to 'INSTEP'.
However, I am unsure how the anagram is indicated.
'used' is the link.
Can you help me to learn more?
(Other definitions for instep that I've seen before include "Arch we stand on" , "Arch area of the foot" , "Part of foot/shoe" , "Part of foot between toes and ankle" , "downtrodden area" .)
