Dirty electrical connection? (5)
I believe the answer is:
earth
This clue might be a double definition.
'dirty' is the first definition.
The definition and answer can be both to do with contact as well as being verbs in their base form.
Perhaps you can see a link between them that I don't see?
'electrical connection?' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for earth that I've seen before include "Make electrics safe" , "Soil; planet" , "Meek's inheritance" , "wire" , "Fox's underground lair" .)
