Tennis stars involved in broadcasting (5)
I believe the answer is:
seeds
'tennis stars' is the definition.
The definition and answer can be both people as well as being plural nouns.
Maybe you can see an association between them that I don't see?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for seeds that I've seen before include "Favoured entrants in a knock-out competition" , "Small hard fruits" , "nuts" , "top tennis players" , "Genesis" .)
