Do without - resisting id, then? (6)
I believe the answer is:
forego
'do' is the definition.
The definition and answer can be both to do with fundamental existence as well as being verbs in their base form.
Maybe you can see a link between them that I can't see?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for forego that I've seen before include "Take precedence" , "Precede (in place/time)" , "Get ahead" , "Manage without" , "Surrender" .)
