Where spaceman goes is delightful! (3,2,4,5)
I believe the answer is:
out of this world
'delightful' is the definition.
(I've seen this before)
'where spaceman goes is' is the wordplay.
I cannot quite understand how this works, but
'is' is within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for out of this world that I've seen before include "Delightful" , "Are stars so" , "Astronauts are sometimes" , "ET was" , "Where spaceships are heading" .)
