Relaxes with Latin during day in Rome (5)
I believe the answer is:
idles
'relaxes' is the definition.
(I've seen this in another clue)
'latin during day in rome' is the wordplay.
'latin' becomes 'l'.
'during' is an insertion indicator.
'day in rome' becomes 'ides' (Roman calendar term, as in the Ides of March).
'l' going within 'ides' is 'IDLES'.
'with' acts as a link.
(Other definitions for idles that I've seen before include "Lazes around" , "Does little, just ticks over" , "Wastes time" , "Avoids working" , "Of engine, just ticks over in neutral" .)
