Right country for Caesar maybe (5)
I believe the answer is:
roman
'caesar maybe' is the definition.
(as in Julius Caesar)
'right country' is the wordplay.
'right' becomes 'r' (common abbreviation).
'country' becomes 'oman' (Oman is an example).
'r'+'oman'='ROMAN'
'for' acts as a link.
(Other definitions for roman that I've seen before include "Our alphabet; upright type" , "Dominant political power of first centuries AD" , "Like the English alphabet" , "A novel" , "Of an Italian city" .)
