React like many given a terrible scare (6)
I believe the answer is:
scream
'react' is the definition.
Although both the answer and definition are verbs in their base form, I don't see how they can define each other.
'many given a terrible scare' is the wordplay.
'many' becomes 'm' (Roman numeral for a thousand).
'given' says to put letters next to each other.
'a terrible' indicates anagramming the letters.
'scare' anagrammed gives 'screa'.
'm' put after 'screa' is 'SCREAM'.
'like' acts as a link.
Can you help me to learn more?
(Other definitions for scream that I've seen before include "Make a piercing sound" , "Hilarious character" , "Scar me (anag)" , "Sound terrified" , "Howl, shriek" .)
