Start of powerful big film about Troy, not gut-wrenching (6)
I believe the answer is:
peptic
'not gut-wrenching' is the definition.
I can't judge whether this defines the answer.
'start of powerful big film about troy' is the wordplay.
'start of' suggests taking the first letters.
'big film' becomes 'epic'.
'about' indicates putting letters inside.
'troy' becomes 't' (abbreviation - troy is a unit of weight).
The first letter of 'powerful' is 'p'.
'epic' going around 't' is 'eptic'.
'p'+'eptic'='PEPTIC'
Can you help me to learn more?
(Other definitions for peptic that I've seen before include "of the digestive system" , "may be aiding digestion" , "Relating to digestion - kind of ulcer" , "Of digestion, and a related ulcer" , "This ulcer is in the stomach or duodenum" .)
