Early bird laid out with fruit (5)
I believe the answer is:
berry
'fruit' is the definition.
(thesaurus)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for berry that I've seen before include "Small juicy fruit" , "'One might be straw, rasp or blue, say (5)'" , "Small edible fruit" , "eg Chuck or Halle" , "Romeo's family" .)
