Medic with very little cash for drug supplier (4)
I believe the answer is:
drip
'drug supplier' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'medic with very little cash' is the wordplay.
'medic' becomes 'dr' (doctor).
'with very little cash' becomes 'ip' (I can't explain this - if you can you should give a lot more credence to this answer).
'dr'+'ip'='DRIP'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for drip that I've seen before include "Leak from tap" , "Drop, ineffective person" , "Fall as from leaky tap" , "Hospital device; weak person" , "Means of intravenous feeding" .)
