Shoot adaptation around Malin Head, as it's as flat as a pancake (6)
I believe the answer is:
smooth
'it's as flat as a pancake' is the definition.
I can't judge whether this defines the answer.
'shoot adaptation around malin head' is the wordplay.
'shoot adaptation' becomes 'sooth' (I can't explain this - if you can you should believe this answer much more).
'around' is an insertion indicator.
'head' indicates taking the first letters.
The first letter of 'malin' is 'm'.
'sooth' placed around 'm' is 'SMOOTH'.
'as' is the link.
Can you help me to learn more?
(Other definitions for smooth that I've seen before include "Having even surface with no projections" , "Calm" , "Free from roughness, bumps etc." , "Suavely charming" , "Not rough or wrinkled" .)
