Slyly outlaw every other one returning from the island (5)
I believe the answer is:
atoll
'the island' is the definition.
(I've seen this in another clue)
'slyly outlaw every other one returning' is the wordplay.
'every other' means one should take alternating letters (every other letter).
'one returning' says the letters should be written in reverse.
'slyly'+'outlaw'='slylyoutlaw'
The alternate letters of 'slylyoutlaw' are 'llota'.
'llota' in reverse letter order is 'ATOLL'.
'from' is the link.
(Other definitions for atoll that I've seen before include "Bikini, say" , "land threatened by rising sea levels" , "Land around a lagoon, such as Bikini" , "Ring-shaped coral reef enclosing a lagoon" , "tropical paradise?" .)
