Betrays celebrity on the rise (4)
I believe the answer is:
rats
'betrays' is the definition.
The definition and answer can be both to do with social activities as well as being verbs in their -s form.
Maybe there's an association between them I don't understand?
'celebrity on the rise' is the wordplay.
'celebrity' becomes 'star' (a star is a celebrity or famous person).
'on the rise' shows that the letters should be reversed in order (in a down clue, letters go up).
'star' written backwards gives 'RATS'.
Can you help me to learn more?
(Other definitions for rats that I've seen before include "(Hunts) rodents - expression of irritation" , "Tells" , "Mild oath - sewer residents" , "First word of 'The 21 19'" , "Rodent pests" .)
