Slide off and move laterally (5)
I believe the answer is:
sidle
'move laterally' is the definition.
'sidle' can be an answer for 'move' (sidling is a kind of moving). I am not sure about the 'laterally' bit.
'slide off' is the wordplay.
'off' is an anagram indicator.
'slide' anagrammed gives 'SIDLE'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for sidle that I've seen before include "Walk obliquely" , "sidewalk" , "Move crabwise" , "Move along sideways" , "Edge along furtively" .)
