Player from United with model back in apartment (8)
I believe the answer is:
flautist
'player' is the definition.
(flautist is a kind of player)
'united with model back in apartment' is the wordplay.
'united' becomes 'u'.
'with model' becomes 'sit' ('sit' can be a synonym of 'model'. I am not sure about the 'with' bit.**).
'back' shows that the letters should be reversed in order.
'in' is an insertion indicator.
'apartment' becomes 'flat' ('flat' can be a synonym of 'apartment').
'sit' reversed gives 'tis'.
'u'+'tis'='utis'
'utis' placed inside 'flat' is 'FLAUTIST'.
'from' is the link.
Can you help me to learn more?
(Other definitions for flautist that I've seen before include "James Galway, say" , "Musician" , "Player of the flute" , "Studio recording period" , "Player of wind instrument" .)
