Made a noise and was detected (7)
I believe the answer is:
rumbled
'made' is the definition.
The answer and definition can be both to do with communicating as well as being past participle verbs.
Perhaps there's an association between them I don't understand?
'a noise and was detected' is the wordplay.
I cannot quite see how this works, but
'noise' could be 'rumble' (rumble is a kind of noise) and 'rumble' is present in the answer.
A single letter 'd' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for rumbled that I've seen is " Saw through - what the thunder did".)
