Enormous thug escaped imprisonment (4)
I believe the answer is:
huge
'enormous' is the definition.
(synonyms)
'thug escaped imprisonment' is the wordplay.
'HUGE' is hidden in amongst the letters.
But, I'm not sure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for huge that I've seen before include "Gigantic" , "Mammoth" , "giant" , "Extremely large" , "Great in size or amount" .)
