Dad has no wood to make a fine display! (7)
I believe the answer is:
panoply
'a fine display' is the definition.
'panoply' can be an answer for 'display' (I have seen 'Impressive display ' mean 'panoply' so perhaps 'display' could also mean 'panoply'). I'm not sure about the 'a fine' bit.
'dad has no wood' is the wordplay.
'dad' becomes 'pa' (pa can mean someone's father).
'has' is a charade indicator (letters next to each other).
'wood' becomes 'ply' (I am not sure about this - if you are sure you should believe this answer much more).
'pa'+'no'+'ply'='PANOPLY'
'to make' is the link.
Can you help me to learn more?
(Other definitions for panoply that I've seen before include "Trappings" , "Wide range" , "A complete or splendid array" , "Apply no mix to splendid array" , "Superb array; suit of armour" .)
