Former statesman and astronaut’s body's pronounced sound (6)
I believe the answer is:
nasser
'sound' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see a link between them that I can't see?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for nasser that I've seen before include "UAR president" , "old Egyptian leader" , "Former President of Egypt" , "Egyptian president, d. 1970" , "-- Hussain, ex-cricketer" .)
