Terror seen around the world makes one hesitate (7)
I believe the answer is:
forbear
'hesitate' 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 there's a link between them I don't understand?
'terror seen around the world' is the wordplay.
'terror' becomes 'fear' (I've seen this before).
'seen around' means one lot of letters goes inside another.
'the world' becomes 'orb' (I have seen 'The World' mean 'orb' so perhaps 'world' could also mean 'orb').
'fear' enclosing 'orb' is 'FORBEAR'.
'makes one' is the link.
Can you help me to learn more?
(Other definitions for forbear that I've seen before include "Abstain" , "Be patient" , "Hold back" , "Refrain from doing something" .)
