Out of bounds? Trendy form of punishment covers it (8)
I believe the answer is:
infinite
'out of bounds?' is the definition.
Both the definition and answer are adjectives. Maybe there's an association between them I don't understand?
'trendy form of punishment covers it' is the wordplay.
'trendy' becomes 'in' ('in' can mean fashionable).
'form of punishment' becomes 'fine' (someone may be fined as a punishment).
'covers' is an insertion indicator.
'fine' enclosing 'it' is 'finite'.
'in'+'finite'='INFINITE'
Can you help me to learn more?
(Other definitions for infinite that I've seen before include "Unrestricted" , "Having no beginning or end" , "Unbounded" , "Unlimited" , "Endless" .)
