Once more turning up in Niagara (5)
I believe the answer is:
again
'once more' is the definition.
(synonyms)
'turning up in niagara' is the wordplay.
'AGAIN' is hidden backwards in amongst the letters.
But, I'm uncertain how this is indicated.
Can you help me to learn more?
(Other definitions for again that I've seen before include "Ocne more" , "Repeatedly" , "return" , "'Another time, once more (5)'" , "repeat order" .)
