Dissimilar to lolly wrappers? Probably not! (8)
I believe the answer is:
unlikely
'probably not' is the definition.
I can't tell whether this defines the answer.
'dissimilar to lolly wrappers?' is the wordplay.
'dissimilar to' becomes 'unlike' (I've seen this in another clue).
'wrappers?' suggests removing the centre (I've seen 'wrappers' mean this).
'lolly' with its centre taken out is 'ly'.
'unlike'+'ly'='UNLIKELY'
Can you help me to learn more?
(Other definitions for unlikely that I've seen before include "Hardly going to happen, improbable" , "Not probable, really the reverse" , "Implausible" , "suspect" , "Slim" .)
