Ruined by having ice added? (2,3,5)
I believe the answer is:
on the rocks
'ruined' is the definition.
(I've seen this before)
'having ice added?' is the wordplay.
I cannot really understand how this works, but
'ice' could be 'rocks' (I've seen this before) and 'rocks' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'by' acts as a link.
Can you help me to learn more?
(Other definitions for on the rocks that I've seen before include "Served with ice - in a state of ruin" , "In trouble - with ice cubes" , "Served neat with ice" , "In trouble and failing" , "Having problems" .)
