Easily walk miles in Italian island heading north (5)
I believe the answer is:
amble
'easily walk' is the definition.
'amble' can be an answer for 'walk' (ambling is a kind of walking). I am not sure about the 'easily' bit.
'miles in italian island heading north' is the wordplay.
'miles' becomes 'm' (common abbreviation).
'in' means one lot of letters goes inside another.
'italian island' becomes 'Elba' (Elba is an Italian island).
'heading north' says the letters should be written backwards (in a down clue, letters go up).
'm' placed into 'elba' is 'elbma'.
'elbma' back-to-front is 'AMBLE'.
Can you help me to learn more?
(Other definitions for amble that I've seen before include "Stroll, saunter" , "Walk in a leisurely fashion" , "Make slow progress" , "Swan" , "Wander gently along" .)
