To avoid it people may go into it (6)
I believe the answer is:
hiding
'it' is the definition.
The definition suggests a singular noun which matches the answer.
'to avoid it people may go' is the wordplay.
I cannot quite understand how this works, but
'go' could be 'din' (dinning is a kind of going) and 'din' is found within the answer.
This explanation may well be incorrect...
'into' acts as a link.
Can you help me to learn more?
(Other definitions for hiding that I've seen before include "Hushing up" , "Concealment - punishment" , "big defeat" , "Harm, damage" , "Evading capture," .)
