Referring to river bank rain pair recollected (8)
I believe the answer is:
riparian
'referring to river' is the definition.
(riparian means relating to river banks)
'rain pair recollected' is the wordplay.
'recollected' is an anagram indicator (letters recollected and rearranged).
'rain'+'pair'='rainpair'
'rainpair' is an anagram of 'RIPARIAN'.
'bank' acts as a link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for riparian that I've seen before include "living by the river" , "near a river" , "Relating to a river bank" , "Relating to a riverbank - Iran pair (anag)" , "associated with banks" .)
