Cashier provides setting for artist versus nomad (9)
I believe the answer is:
traveller
'cashier' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'setting for artist versus nomad' is the wordplay.
'setting for' is an insertion indicator (inserted letters are set inside others).
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'versus' becomes 'v'.
'nomad' becomes 'teller' (I can't justify this - if you can you should believe this answer much more).
'ra'+'v'='rav'
'rav' put within 'teller' is 'TRAVELLER'.
'provides' is the link.
Can you help me to learn more?
(Other definitions for traveller that I've seen before include "Gypsy" , "One on a trip" , "description of Stevenson or his donkey?" , "She goes around" , "becoming less narrow-minded over time?" .)
