Flower from Frank Sinatra wanting Nat King ... (7)
I believe the answer is:
freesia
'flower' is the definition.
(type of flower)
'frank sinatra wanting nat king' is the wordplay.
I cannot quite understand how this works, but
'frank' could be 'free' (I've seen this in other clues) and 'free' is present in the answer.
The remaining letters 'sia' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'from' acts as a link.
Can you help me to learn more?
(Other definitions for freesia that I've seen before include "Fragrant-flowered plant; faeries (anag.)" , "Scented plant from South Africa" , "Scented South African plant" , "bloomer" , "Sea rife with these odd flowers" .)
