Falling into everything (3)
I believe the answer is:
all
'everything' is the definition.
(all things)
'falling' is the wordplay.
'ALL' is hidden within the letters.
However, I'm not sure how the hidden word is indicated.
'into' is the link.
Can you help me to learn more?
(Other definitions for all that I've seen before include "Entirely; everyone" , "Entire" , "Garden passage between trees or bushes" , "in toto" , "Straight garden path" .)
