Impetuous youngster not at home following meal, right? (8)
I believe the answer is:
tearaway
'impetuous' is the definition.
(synonyms)
'not at home following meal right?' is the wordplay.
'not at home' becomes 'away' (I've seen this before).
'following' means one lot of letters go next to another.
'meal' becomes 'tea' (tea is a kind of meal).
'right?' becomes 'r' (common abbreviation).
'tea'+'r'='tear'
'away' put after 'tear' is 'TEARAWAY'.
'youngster' acts as a link.
This may not be right. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for tearaway that I've seen before include "Unruly, impetuous person" , "Hothead" , "reckless type" , "Unruly youth" , "Yob" .)
