Grass found at the bank! (6)
I believe the answer is:
teller
'bank' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for teller that I've seen before include "Edward ---, physicist; vote-counter" , "Counter of votes or a bank employee" , "One who instructs" , "One records cash" , "one reckons" .)
