American comedian has a role in baseball (6)
I believe the answer is:
fields
'american comedian has' is the definition.
The answer and definition can be both to do with communicating as well as being verbs in their -s form.
Perhaps you can see a link between them that I can't see?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for fields that I've seen before include "Gracie or WC?" , "much-loved singer" , "See 25 Down" , "Areas of farmland" , "Enclosed pieces of land" .)
