Flexible Ena takes walk round (8)
I believe the answer is:
amenable
'flexible' is the definition.
(I've seen this before)
'ena takes walk round' is the wordplay.
'takes' means one lot of letters goes inside another (take can mean to capture or invade).
'walk round' becomes 'amble' (amble is a kind of walk. I am not sure about the 'round' bit.).
'ena' placed into 'amble' is 'AMENABLE'.
Can you help me to learn more?
(Other definitions for amenable that I've seen before include "Prepared to fall in with others' plans" , "Pliant" , "Easily influenced" , "Agreeable and accommodating" , "Open to suggestions" .)
