Dance as Bedouin in his element? (8)
I believe the answer is:
saraband
'dance' is the definition.
(saraband is a kind of dance)
'bedouin in his element?' is the wordplay.
'bedouin' becomes 'arab'.
'in' means one lot of letters goes inside another.
'his element?' becomes 'sand' (I can't justify this - if you can you should believe this answer much more).
'arab' inserted into 'sand' is 'SARABAND'.
'as' acts as a link.
(Other definitions for saraband that I've seen before include "dance music" , "Old, courtly dance" , "Slow Spanish dance" , "Stately dance" .)
