The roots of one child's game wrapped up in the present (8)
I believe the answer is:
heritage
'the roots of' is the definition.
The definition suggests a singular noun which matches the answer.
'one child's game wrapped up in the present' is the wordplay.
'one' becomes 'i' (Roman numeral).
'child's game' becomes 'tag' (tag is a kind of child's game).
'wrapped up in' is an insertion indicator.
'the present' becomes 'here' (I've seen this before).
'i'+'tag'='itag'
'itag' inserted into 'here' is 'HERITAGE'.
Can you help me to learn more?
(Other definitions for heritage that I've seen before include "Our historic legacy" , "Objects and cultural traditions passed down" , "historical collection?" , "Received culture and background" , "Birth-related condition" .)
