Oddly carved tree found in Mediterranean location (5)
I believe the answer is:
crete
'mediterranean location' is the definition.
'crete' can be an answer for 'location' (I have seen 'European location' mean 'crete' so perhaps 'location' could also mean 'crete'). I am not certain of the 'mediterranean' bit.
'oddly carved tree' is the wordplay.
'oddly' indicates alternate letters (letters in odd-numbered positions).
'carved'+'tree'='carvedtree'
The alternating letters of 'carvedtree' are 'CRETE'.
'found in' acts as a link.
Can you help me to learn more?
(Other definitions for crete that I've seen before include "Mediterranean island with Minoan remains" , "Largest Greek island" , "Island Germans took, 1941" , "Large island in Med" , "Knossos island" .)
