'another time' is the definition.
(synonyms)

'returning from niagara' is the wordplay.
'AGAIN' is hidden backwards in amongst the letters.

Can you help me to learn more?

(Other definitions for again that I've seen before include "Repeatedly" , "One more time, encore" , "Predictably perhaps" , "Moreover - a second time" , "Next time" .)

I've seen this clue in the Evening Standard.
