Roast a nut specially for distant traveller (9)
I believe the answer is:
astronaut
'distant traveller' is the definition.
'astronaut' can be an answer for 'traveller' (astronaut is a kind of traveller). I'm unsure of the 'distant' bit.
'roast a nut specially' is the wordplay.
'specially' indicates an anagram (I've seen this in other clues).
'roast'+'a'+'nut'='roastanut'
'roastanut' is an anagram of 'ASTRONAUT'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for astronaut that I've seen before include "heavenly voyager" , "Person trained to travel in a spacecraft" , "High-flyer" , "Santa tour for space traveller" , "Buzz Aldrin, for example" .)
