Futile to reduce consumption? (7)
I believe the answer is:
useless
'futile' is the definition.
(similar in meaning)
'reduce consumption?' is the wordplay.
I cannot quite understand how this works, but
'consumption?' could be 'use' (synonyms) and 'use' is present in the answer.
The remaining letters 'less' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for useless that I've seen before include "Of no benefit" , "Far from impressive" , "Serving no practical purpose" , "Futile and unavailing" , "Unemployable" .)
