Wanders away from the street lights (6)
I believe the answer is:
strays
'wanders away' is the definition.
'strays' can be an answer for 'wanders' (I've seen this in another clue). I'm unsure of the 'away' bit.
'street lights' is the wordplay.
'street' becomes 'st' (abbreviation).
'lights' becomes 'rays' (I am not sure about this - if you are sure you should believe this answer much more).
'st'+'rays'='STRAYS'
'from the' acts as a link.
Can you help me to learn more?
(Other definitions for strays that I've seen before include "Wanders off with satyrs" , "Goes off course" , "Gets lost, wanders away from the track" , "Wanders off course" , "Wanders off the path, gets lost" .)
