As eaten, for instance, by a gang leader? (3)
I believe the answer is:
egg
'as eaten for instance by a gang leader?' is the definition.
I can't judge whether this definition defines the answer.
'for instance by a gang leader?' is the wordplay.
'for instance' becomes 'eg' (synonyms).
'by' says to put letters next to each other.
'leader?' suggests taking the first letters (I've seen 'leaders' mean this).
The initial letter of 'gang' is 'g'.
'eg'+'g'='EGG'
Can you help me to learn more?
(Other definitions for egg that I've seen before include "Mine (slang)" , "Quiche ingredient" , "Reproductive part" , "The advertising slogan exhorted us to go to work on one" , "Early stage of development" .)
