Expect opposition given radical stance no-one backs (7)
I believe the answer is:
foresee
'expect' is the definition.
(I've seen this before)
'opposition given radical stance no-one backs' is the wordplay.
'opposition' becomes 'foe' (I've seen this in another clue).
'given' means one lot of letters goes inside another.
'radical stance no' becomes 'res' (I can't explain this - if you can you should believe this answer much more).
'backs' suggests the final letters (I've seen 'back' mean this).
The final letter of 'one' is 'e'.
'foe' enclosing 'res' is 'forese'.
'forese'+'e'='FORESEE'
Can you help me to learn more?
(Other definitions for foresee that I've seen before include "Anticipate" , "witness in advance?" , "divine" , "Expect" , "Prognosticate" .)
