What account providers do managed to raise amount of interest? (7)
I believe the answer is:
narrate
'what account providers do' is the definition.
The definition suggests a singular noun but the answer is not.
'managed to raise amount of interest?' is the wordplay.
'managed' becomes 'ran' (I've seen this in another clue).
'to raise' says the letters should be written in reverse (in a down clue, letters go up).
'amount of interest?' becomes 'rate' (I can't explain this - if you can you should believe this answer much more).
'ran' back-to-front is 'nar'.
'nar'+'rate'='NARRATE'
Can you help me to learn more?
(Other definitions for narrate that I've seen before include "Provide commentary" , "Tell a story, recite" , "Rare ant (anag.)" , "Tell the tale." , "Tell us the story" .)
