'concealing' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see an association between them that I don't see?

'secret place? no way' is the wordplay.
'secret' becomes 'occult' (synonyms).
'place? no' becomes 'atio' (I am not sure about this - if you are sure you should believe this answer much more).
'way' becomes 'n' (Compass direction - North).
'occult'+'atio'+'n'='OCCULTATION'
