Hot girls went out around Spain (10)
I believe the answer is:
sweltering
'hot' is the definition.
('sweltering' can be similar in meaning to 'hot')
'girls went out around spain' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'around' means one lot of letters goes inside another.
'spain' becomes 'e' (abbreviation for Espana).
'girls'+'went'='girlswent'
'girlswent' with letters rearranged gives 'swltering'.
'swltering' going around 'e' is 'SWELTERING'.
(Other definitions for sweltering that I've seen before include "getting uncomfortably hot" , "Hot and humid" , "hot and sweaty" , "getting unpleasantly hot" .)
