Magical being, not fine and delicate (4)
I believe the answer is:
airy
'delicate' is the definition.
(thesaurus)
'magical being not fine' is the wordplay.
'magical being' becomes 'fairy' (I've seen this before).
'not' suggests deleting specific letters.
'fine' becomes 'f' (abbreviation).
'fairy' with 'f' taken away is 'AIRY'.
'and' is the link.
(Other definitions for airy that I've seen before include "Open and spacious" , "open to the sky" , "Old astronomer" , "Delicate; dismissive" , "Well ventilated; insubstantial" .)
