Setter wanders up to see native people (5)
I believe the answer is:
maori
'native people' is the definition.
(I've seen this before)
'setter wanders up' is the wordplay.
'setter' becomes 'I' (the person who set this crossword).
'wanders' becomes 'roam' (I can't explain this - if you can you should believe this answer much more).
'up' is a reversal indicator (in down clue: letters go upwards).
'i'+'roam'='iroam'
'iroam' reversed gives 'MAORI'.
'to see' is the link.
Can you help me to learn more?
(Other definitions for maori that I've seen before include "A native from the south" , "Native New Zealander of Polynesian origin" , "Aborigine of New Zealand" , "One of New Zealand's aboriginal people" , "NZ people" .)
