Frisky collie gets only half of sweet treat (3,5)
I believe the answer is:
ice lolly
'sweet treat' is the definition.
'ice lolly' can be an answer for 'treat' (I have seen 'Frozen treat' mean 'ice lolly' so perhaps 'treat' could also mean 'ice lolly'). I'm unsure of the 'sweet' bit.
'frisky collie gets only half' is the wordplay.
'frisky' indicates anagramming the letters.
'gets' is a charade indicator (letters next to each other).
'half' means to take half the letters.
'only' halved is 'ly'.
'collie' anagrammed gives 'icelol'.
'icelol'+'ly'='ICE-LOLLY'
'of' is the link.
Can you help me to learn more?
(Other definitions for ice lolly that I've seen before include "It's frozen on a small wooden stick" , "Frozen treat" , "Frozen confection" , "'Frozen sweet on a stick (3,5)'" , "summer treat" .)
