Sailors from America in southern Turkey (6)
I believe the answer is:
tarsus
'southern turkey' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'sailors from america' is the wordplay.
'sailors' becomes 'tars' (tar is a kind of sailor).
'from america' becomes 'us'.
'tars'+'us'='TARSUS'
'in' is the link.
Can you help me to learn more?
(Other definitions for tarsus that I've seen before include "Group of bones" , "The seven bones of the upper foot and ankle" , "Saul of ......" , "biblical city" , "Bones of the ankle and heel" .)
