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

'fruit' is the definition.
(I've seen this before)

I cannot understand how the remainder of the clue works.

(Other definitions for etaerio that I've seen before include "An aggregated fruit" , "Aggregate fruit" .)

I've seen this clue in The Times and The Sunday Times.
