Dig that house! (5)
I believe the answer is:
lodge
This clue might be a double definition.
'dig' is the first definition.
The definition and answer can be both to do with contact as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?
'that house' is the second definition.
(lodge is a kind of house)
Can you help me to learn more?
(Other definitions for lodge that I've seen before include "Stay temporarily, with bed and board" , "Small gatehouse" , "residence" , "House in the wilds" , "Lair of beaver or otter" .)
