Youngster of little importance? (5)

I believe the answer is:

minor

I believe this clue is a double definition.

'youngster' is the first definition.
(synonyms)

'of little importance?' is the second definition.
(minor can mean unimportant)

(Other definitions for minor that I've seen before include "Young person below voting age" , "Of small importance" , "Of less importance" , "Deceptively realistic (art)" , "Not major" .)

I've seen this clue in the Evening Standard.
