For example, good kind of person (3)
I believe the answer is:
egg
'kind of person' is the definition.
'egg' can be an answer for 'person' (as in 'a bad egg'). I am not certain of the 'kind of' bit.
'for example good' is the wordplay.
'for example' becomes 'e.g.' (short for 'exempli gratia', 'for example' in Latin).
'good' becomes 'g' (abbreviation).
'eg'+'g'='EGG'
Can you help me to learn more?
(Other definitions for egg that I've seen before include "It, or chicken, first?" , "Bomb or mine (sl.)" , "It comes before or after the chicken?" , "Hen fruit" , "Reproductive part" .)
