Wander round Mediterranean island, taking in another one briefly (5)
I believe the answer is:
amble
'wander round mediterranean island' is the definition.
'amble' can be an answer for 'wander' (thesaurus). I'm unsure of the 'round mediterranean island' bit.
'in another one briefly' is the wordplay.
'in' means one lot of letters goes inside another.
'another' becomes 'able' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'one' becomes 'me' (a setter might use 'one' to humourously mean 'me').
'briefly' means to remove the last letter.
'me' with its last letter removed is 'm'.
'able' enclosing 'm' is 'AMBLE'.
'taking' acts as a link.
Can you help me to learn more?
(Other definitions for amble that I've seen before include "Walk gently" , "Take leisurely stroll" , "Relaxed walk" , "Go at a leisurely gait" , "Dawdle" .)
