No expression of contentment from boat-builder (4)
I believe the answer is:
noah
'boat-builder' is the definition.
(I've seen this before)
'no expression of contentment' is the wordplay.
'expression of contentment' becomes 'ah' (I can't justify this - if you can you should give a lot more credence to this answer).
'no'+'ah'='NOAH'
'from' is the link.
Can you help me to learn more?
(Other definitions for noah that I've seen before include "A very early sailor" , "Hebrew patriarch who survived the Flood" , "Great Biblical boatman" , "Historic sailor" , "Oh, an ark man" .)
