Pop Lee's eccentric family? (6)
I believe the answer is:
people
'family?' is the definition.
(I know that people is a type of family)
'pop lee's eccentric' is the wordplay.
'eccentric' indicates anagramming the letters.
'pop'+'lee'='poplee'
'poplee' anagrammed gives 'PEOPLE'.
(Other definitions for people that I've seen before include "Population" , "Humans in general" , "Humankind" , "Race - mankind" , "Nation" .)
