Priest and doctor requiring some fluids (5)
I believe the answer is:
druid
'priest' is the definition.
(druid is a kind of priest)
'doctor requiring some fluids' is the wordplay.
I cannot quite understand how this works, but
'doctor' could be 'dr' (abbreviation) and 'dr' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'and' acts as a link.
Can you help me to learn more?
(Other definitions for druid that I've seen before include "Ancient priest of Wales" , "old magician?" , "Ancient Celt priest" , "Ancient Celtic priest" , "Pre-Christian Celtic priest" .)
