Some fruit on ice that's added to gin? (5)
I believe the answer is:
tonic
'added to gin?' is the definition.
I can't judge whether this definition defines the answer.
'some fruit on ice' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'TONIC' is hidden in the letters of 'fruit on ice'.
'that's' is the link.
Can you help me to learn more?
(Other definitions for tonic that I've seen before include "do for musicians" , "An enlivener" , "makes you feel good?" , "requirement for invigoration?" , "A pick-me-up drink, nice with gin" .)
