A friend has new ideas for making a fence (8)
I believe the answer is:
palisade
'a fence' is the definition.
(I know that fence can be written as palisade)
'a friend has new ideas' is the wordplay.
'a friend' becomes 'pal' (pal can mean a friend).
'has' is a charade indicator (letters next to each other).
'new' indicates anagramming the letters.
'ideas' anagrammed gives 'isade'.
'pal'+'isade'='PALISADE'
'for making' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for palisade that I've seen before include "Fence of stakes or iron railings" , "Enclosure of stakes" , "Fence of wooden stakes" , "means of defence" , "fencing" .)
