Vital editing badly requiring input of a tech-savvy youngster (7,6)
I believe the answer is:
digital native
'vital editing badly requiring input' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'a tech-savvy youngster' is the wordplay.
I cannot really understand how this works, but
'a' is within the answer.
'savvy' could be 'dig' (synonyms) and 'dig' is located in the answer.
This explanation may well be incorrect...
'of' acts as a link.
Can you help me to learn more?
(Another definition for digital native that I've seen is " Millennial".)
