Senior citizen could drive, taking regular breaks (5)
I believe the answer is:
oldie
This could be a double definition.
'senior citizen' is the first definition.
(I've seen this before)
'drive taking regular breaks' is the second definition.
The definition suggests a singular noun which matches the answer.
'could' acts as a link.
Can you help me to learn more?
(Other definitions for oldie that I've seen before include "Senior citizen" , "Aged person or thing" , "Mature person; magazine" , "Venerable person/thing" , "classic film perhaps" .)
