Complain against the repetitiveness? (6)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
murmur
'complain' is the definition.
(murmuring is a kind of complaining)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for murmur that I've seen before include "Abnormal sound made by heart" , "Speak softly or indistinctly" , "Speak in a low voice, whisper" , "Quietly spoken utterance; heart defect" , "Low continuous sound" .)
