I'm a little stuck... Click here to teach me more about this clue!

'fruit' is the definition.
(berry is a kind of fruit)

I can't explain the remainder of the clue.

(Other definitions for berry that I've seen before include "Small juicy fruit" , "eg Chuck or Halle" , "'One might be straw, rasp or blue, say (5)'" , "Word linking black or blue" , "Smal pulpy fruit" .)

I've seen this clue in The Times.
