To curve and raise (4)
I believe the answer is:
arch
This clue could be a double definition.
'to curve' is the first definition.
('arch' can be a synonym of 'curve')
'raise' is the second definition.
The definition and answer can be both to do with motion as well as being verbs in their base form.
Perhaps you can see an association between them that I can't see?
'and' acts as a link.
Can you help me to learn more?
(Other definitions for arch that I've seen before include "Curved vault" , "Foremost" , "Curved gateway" , "Curved shape that spans an opening" , "Curved part of stone bridge, perhaps" .)
