Barrel made from wood of the pine family? (6)
I believe the answer is:
firkin
'barrel' is the definition.
(I know that firkin is a type of keg)
'wood of the pine family?' is the wordplay.
I cannot quite see how this works, but
'wood' could be 'fir' (fir is a kind of wood) and 'fir' is found in the answer.
'family?' could be 'kin' (synonyms) and 'kin' is found in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'made from' is the link.
Can you help me to learn more?
(Other definitions for firkin that I've seen before include "Small cask for liquids, butter, fish" , "Brewing measure equal to 9 gallons" , "Wooden keg with 9 imperial gallons" , "Small cask formerly used for liquids" , "Cooper's little effort" .)
