Some wedding guests sounded kittenish inside (5)
I believe the answer is:
mewed
'sounded kittenish inside' is the definition.
The definition and answer 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?
'some wedding guests' is the wordplay.
'MEWED' is hidden in amongst the letters.
However, I am uncertain how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for mewed that I've seen before include "Made cat noise" , "cried pitifully" , "made catty remark" , "confined" .)
