As oldest pair err in famous poem? (8,4)
I believe the answer is:
paradise lost
'famous poem?' is the definition.
'Paradise Lost' can be an answer for 'poem?' (epic poem by John Milton). I am not certain of the 'famous' bit.
'as oldest pair err' is the wordplay.
'err' is an anagram indicator.
'as'+'oldest'+'pair'='asoldestpair'
'asoldestpair' is an anagram of 'PARADISE LOST'.
'in' is the link.
Can you help me to learn more?
(Other definitions for paradise lost that I've seen before include "Epic poem by Milton" , "Poem by 1" , "long poem" , "Work by Milton" , "disaster on cosmic scale" .)
