Sound from above? This is missing below (7)
I believe the answer is:
thunder
'sound' is the definition.
(I know that thunder is a type of natural sound)
'this is missing below' is the wordplay.
'missing' is a deletion indicator.
'below' becomes 'under' (synonyms).
'this' with 'is' taken out is 'th'.
'th'+'under'='THUNDER'
'from above?' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for thunder that I've seen before include "Boom; bellow" , "Deep rumbling sound" , "Booming noise from the heavens" , "Hurt Ned (anag) - loud noise" , "Loud and prolonged noise in the sky" .)
