Devil crossing river to see a pal (6)
I believe the answer is:
friend
'a pal' is the definition.
(I've seen this in another clue)
'devil crossing river' is the wordplay.
I cannot quite understand how this works, but
'river' could be 'r' (abbreviation for river) and 'r' is located in the answer.
'devil' could be 'fiend' (synonyms) and 'fiend' is present in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'to see' is the link.
Can you help me to learn more?
(Other definitions for friend that I've seen before include "Companion; Quaker" , "Person with whom you have a bond of mutual affection" , "allowed to pass by the guard" , "Organisation's supporter" , "Buddy, chum" .)
