Satisfactory friend put on a list (9)
I believe the answer is:
palatable
'satisfactory' is the definition.
Both the answer and definition are adjectives. Maybe you can see a link between them that I can't see?
'friend put on a list' is the wordplay.
'friend' becomes 'pal' (pal can mean a friend).
'put on' means one lot of letters go next to another.
'list' becomes 'table' (list can mean a table or chart).
'pal'+'a'+'table'='PALATABLE'
Can you help me to learn more?
(Other definitions for palatable that I've seen before include "good to eat" , "Tasty" , "pleasing" , "Pleasant to the taste, acceptable" , "Of food, tasting nice; of idea, acceptable" .)
