Spacewalker missing Wales gets to put clothes back in suitcase again to go home (6)
I believe the answer is:
repack
'spacewalker missing wales gets to put clothes back in suitcase again' is the definition.
I can't tell whether this definition defines the answer.
'to go home' is the wordplay.
'to go' becomes 're' (I've seen this in other clues).
'home' becomes 'pack' (I can't explain this - if you can you should give a lot more credence to this answer).
're'+'pack'='REPACK'
Can you help me to learn more?
(Other definitions for repack that I've seen before include "Fill suitcase again" , "Prepare to leave hotel" , "tidy cases" , "Once again put away" , "rearrange contents" .)
