Moves off and slides away (6)
I believe the answer is:
sidles
'moves off' is the definition.
'sidles' can be an answer for 'moves' (sidling is a kind of moving). I am unsure of the 'off' bit.
'slides away' is the wordplay.
'away' indicates an anagram (letters move away from their original places).
'slides' anagrammed gives 'SIDLES'.
'and' is the link.
Can you help me to learn more?
(Other definitions for sidles that I've seen before include "Moves sideways" , "Move sideways or furtively" , "Walks sideways like crab" , "Approaches obliquely" .)
