It’s scary to carry on endlessly being knocked back (3)
I believe the answer is:
eek
'it's scary' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'carry on endlessly being knocked back' is the wordplay.
'carry on' becomes 'keep'.
'endlessly' means to remove the last letter.
'being knocked back' is a reversal indicator.
'keep' with its final letter taken away is 'kee'.
'kee' reversed gives 'EEK'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for eek that I've seen before include "fearful cry" , "Expression of surprise" , "Expression of mild alarm" , "I'm frightened!" , "Expression of mild fright" .)
