Returning from Niagara, as before (5)
I believe the answer is:
again
'before' is the definition.
Both the definition and answer are adverbs. Perhaps there's an association between them I don't understand?
'returning from niagara' is the wordplay.
'AGAIN' is hidden backwards in amongst the letters.
But, I am unsure how this is indicated.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for again that I've seen before include "Not for the first time" , "second term" , "Here we go ___" , "Ocne more" , "'Another time, once more (5)'" .)
