A strikingly repetitive thing to do (6)
I believe the answer is:
batter
This could be a double definition.
'a strikingly repetitive thing' is the first definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'do' is the second definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for batter that I've seen before include "Pasty liquid - paste" , "Mixture of flour, eggs and milk, used in cooking" , "Strike hard repeatedly" , "Treat violently - pancake mix" , "Make crisp and brown" .)
