Residence right for old Greek (5)
I believe the answer is:
homer
'old greek' is the definition.
'Homer' can be an answer for 'greek' (Homer is an example). I am unsure of the 'old' bit.
'residence right' is the wordplay.
'residence' becomes 'home' (home is a kind of residence).
'right' becomes 'r' (abbreviation).
'home'+'r'='HOMER'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for homer that I've seen before include "Measure < of poet's" , "Pigeon; Greek poet" , "Greek author; pigeon" , "Great Greek poet of the Iliad and the Odyssey" , "Cartoon father of Bart and Lisa" .)
