A campaign to get people to use the roads (5)
I believe the answer is:
drive
I believe this clue is a quadruple definition!!
'a campaign' is the first definition.
(I know this)
'to get' is the second definition.
(I know that drive is a type of pressure)
'people' is the third definition.
The definition and answer can be both to do with fundamental existence as well as being verbs in their base form.
Perhaps you can see a link between them that I can't see?
'to' acts as a link.
'use the roads' is the fourth definition.
'Drive' can be an answer for 'use' (I know this). I am not sure about the 'the roads' bit.
Can you help me to learn more?
(Other definitions for drive that I've seen before include "Propel; outing" , "spin" , "zip" , "Diver (anag.)" , "tenacity" .)
