Copy Martin, perhaps, as a name from an earlier generation (10)
I believe the answer is:
patronymic
'a name from an earlier generation' is the definition.
I can't judge whether this defines the answer.
'copy martin perhaps' is the wordplay.
'perhaps' indicates an anagram.
'copy'+'martin'='copymartin'
'copymartin' with letters rearranged gives 'PATRONYMIC'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for patronymic that I've seen before include "Name derived from forefather" , "Russian middle name" .)
