Cry from one grabbed by green ogre (6)
I believe the answer is:
shriek
'cry' is the definition.
(I know that shriek is a type of cry)
'one grabbed by green ogre' is the wordplay.
'one' becomes 'i' (Roman numeral).
'grabbed by' is an insertion indicator (inserted letters are grabbed inside).
'green ogre' becomes 'Shrek' (film character).
'i' put into 'shrek' is 'SHRIEK'.
'from' is the link.
(Other definitions for shriek that I've seen before include "Yell, screech" , "A high-pitched shrill cry" , "Howl" , "Hikers (anag.)" , "Utter high-pitched cry" .)
