Call it English hill-dweller (7)
I believe the answer is:
termite
'hill-dweller' is the definition.
I can't judge whether this defines the answer.
'call it english' is the wordplay.
'call' becomes 'term' (to term something is to call it something).
'english' becomes 'e' (abbreviation).
'term'+'it'+'e'='TERMITE'
Can you help me to learn more?
(Other definitions for termite that I've seen before include "Mound-dweller" , "It lives on wood" , "Woodworm of warmer regions" , "Wood-eating insect" , "Nest-building insect" .)
