Screech from one grabbed by screen ogre (6)
I believe the answer is:
shriek
'screech' is the definition.
(I know that screech can be written as shriek)
'one grabbed by screen ogre' is the wordplay.
I cannot really see how this works, but
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
'ogre' could be 'shrek' (ogre in the film franchise) and 'shrek' is found in the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'from' acts as a link.
Can you help me to learn more?
(Other definitions for shriek that I've seen before include "A high-pitched shrill cry" , "Yell, screech" , "Scream or squeal" , "Hikers (anag.)" , "Short piercing scream" .)
