Starts with her individual rights, rumbling sound can be heard (5)
I believe the answer is:
'rumbling sound can be heard' is the definition.
I can't tell whether this definition defines the answer.
'starts with her individual rights' is the wordplay.
'starts' suggests taking the first letters.
'rights' becomes 'rr' (two abbreviations for right).
The first letters of 'with her individual' is 'whi'.
Can you help me to learn more?
(Other definitions for whirr that I've seen before include "Sound of rapid spinning or vibrating" , "Humming sound" , "Spin noisily" , "Sound of something rapidly rotating" , "Spinning hum" .)
