I will, for example, join friend in a dodgy way (9)
I believe the answer is:
illegally
'in a dodgy way' is the definition.
I can't judge whether this definition defines the answer.
'i will for example join friend' is the wordplay.
'i will' becomes 'I'll' (abbreviation).
'for example' becomes 'e.g.' (short for 'exempli gratia', 'for example' in Latin).
'join' says to put letters next to each other.
'friend' becomes 'ally' (an ally is a friend or supporter).
'ill'+'eg'+'ally'='ILLEGALLY'
Can you help me to learn more?
(Other definitions for illegally that I've seen before include "Lawlessly" , "In criminal fashion" , "in a criminal manner" , "In a way that breaks the law" , "unlawfully" .)
