Dry run cancelled: help needed (3)
I believe the answer is:
aid
'help needed' is the definition.
I can't judge whether this defines the answer.
'dry run cancelled' is the wordplay.
'dry' becomes 'arid' (similar in meaning).
'run' becomes 'r' (cricket abbreviation).
'cancelled' indicates named letters should be taken away.
'arid' with 'r' taken away is 'AID'.
Can you help me to learn more?
(Other definitions for aid that I've seen before include "Auxiliary" , "Care and help" , "welfare" , "Good point" , "A hand" .)
