Sweet kid thus lighter? Unlikely (7,7)
I believe the answer is:
turkish delight
'sweet' is the definition.
(Turkish Delight is an example)
'kid thus lighter? unlikely' is the wordplay.
'unlikely' is an anagram indicator.
'kid'+'thus'+'lighter'='kidthuslighter'
'kidthuslighter' with letters rearranged gives 'TURKISH DELIGHT'.
(Other definitions for turkish delight that I've seen before include "Confectionery" , "Sweet" , "Jelly-like confection ..." , "consequence of a future decision on EU admission?" , "pleasure in Ankara" .)
