Hold back terror seen around the world (7)
I believe the answer is:
forbear
'hold back' is the definition.
(I know that hold back can be written as forbear)
'terror seen around the world' is the wordplay.
'terror' becomes 'fear' (I've seen this in another clue).
'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'.
(Other definitions for forbear that I've seen before include "Hold back" , "Be patient" , "Refrain from doing something" , "Abstain" .)
