In Cuba, dancing, ten going round very camp (7)
I believe the answer is:
bivouac
'camp' is the definition.
(I know that camp can be written as bivouac)
'in cuba dancing ten going round very' is the wordplay.
'in' means one lot of letters goes inside another.
'dancing' is an anagram indicator.
'ten' becomes 'IO' (IO resembles 10).
'going round' means one lot of letters goes inside another (some letters go around others).
'very' becomes 'v' (abbreviation).
'cuba' with letters rearranged gives 'buac'.
'io' going around 'v' is 'ivo'.
'buac' placed around 'ivo' is 'BIVOUAC'.
(Other definitions for bivouac that I've seen before include "Makeshift camp" , "Temporary camp for soldiers" , "Temporary and basic encampment" , "Camp in the open" , "Encamp" .)
