Crossword Genius

Unemployed star on radio (4)

Ross

I believe the answer is:

idle

'unemployed' is the definition.
('idle' is associated in meaning with 'unemployed')

'star on radio' is the wordplay.
'star' becomes 'idol' (idol is a kind of star).
'on radio' shows a homophone (sound like).
'idol' is a homophone of 'IDLE'.

(Other definitions for idle that I've seen before include "Unoccupied (time); run (engine) slowly" , "Indolent" , "without basis" , "Inactive - lied (anag)" , "Not busy" .)

I've seen this clue in The Telegraph.
