Calls on Latin sex models (6)
I believe the answer is:
visits
'calls on' is the definition.
('visit' can be a synonym of 'call on')
'latin sex models' is the wordplay.
'latin sex' becomes 'vi' (VI in Roman numerals - 'sex' is 'six' in Latin. I am not sure about the 'latin' bit.).
'models' becomes 'sits' ('sit' can be a synonym of 'model').
'vi'+'sits'='VISITS'
Can you help me to learn more?
(Other definitions for visits that I've seen before include "Call to see" , "Comes by, drops in" , "Calls in to see" , "Pays a call" , "Social calls" .)
