Name it, English insect (7)
I believe the answer is:
termite
'insect' is the definition.
(I know that termite is a type of insect)
'name it english' is the wordplay.
'name' becomes 'term' (both can mean a word for something).
'english' becomes 'E' (abbreviation).
'term'+'it'+'e'='TERMITE'
(Other definitions for termite that I've seen before include "Social insect" , "Wood-eating insect" , "Six-footer" , "Mound builder" , "Whitish antlike insect" .)
