A little taken aback, interrupted by chap refusing to back down? (7)
I believe the answer is:
adamant
'refusing to back down?' is the definition.
I can't tell whether this definition defines the answer.
'a little taken aback interrupted by chap' is the wordplay.
'little' becomes 'tad' (both can mean a small amount).
'taken aback' shows that the letters should be reversed in order.
'interrupted by' indicates putting letters inside.
'chap' becomes 'man' (chap can mean a man).
'tad' backwards is 'dat'.
'dat' placed around 'man' is 'damant'.
'a'+'damant'='ADAMANT'
Can you help me to learn more?
(Other definitions for adamant that I've seen before include "Impervious to pleas or persuasion" , "Firm and unyielding" , "Refusing to change opinion" , "Unyielding, won't change mind" , "Stubbornly firm" .)
