Old shipbuilder’s failure to respond to doctor? (4)
I believe the answer is:
noah
'old shipbuilder's' is the definition.
'Noah' can be an answer for 'shipbuilder's' (I have seen 'Biblical shipbuilder' mean 'noah' so perhaps 'shipbuilder' could also mean 'noah'). I am unsure of the 'old' bit.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for noah that I've seen before include "Sailor who ran aground on Mount Ararat" , "He survived 40 days and 40 nights of rain" , "Biblical boat builder" , "Hebrew patriarch who survived the Flood" , "Ham's father" .)
