Noticed sound of some cattle (5)
I believe the answer is:
heard
'noticed sound of some cattle' is the definition.
The answer and definition can be both to do with perception as well as being past participle verbs.
Perhaps you can see a link between them that I don't see?
'sound of some cattle' is the wordplay.
'sound of' shows a homophone (sound like).
'some cattle' becomes 'herd' (herd of cattle).
'herd' is a homophone of 'HEARD'.
Can you help me to learn more?
(Other definitions for heard that I've seen before include "Gathered" , "Was told of" , "Caught - picked up" , "Examined" , "Tried" .)
