Second video game about European astronaut (8)
I believe the answer is:
spaceman
'astronaut' is the definition.
(I know that astronaut can be written as spaceman)
'second video game about european' is the wordplay.
'second' becomes 's' (common abbreviation).
'video game' becomes 'pacman' (I am not sure about this - if you are sure you should believe this answer much more).
'about' indicates putting letters inside.
'european' becomes 'e' (abbreviation e.g. EU).
'pacman' enclosing 'e' is 'paceman'.
's'+'paceman'='SPACEMAN'
Can you help me to learn more?
(Other definitions for spaceman that I've seen before include "High flier" , "one requiring a supply of oxygen?" , "Out-of-this-world chap?" , "Distant traveller" , "Armstrong, perhaps?" .)
