The author Umberto Green? (3)

I believe the answer is:

eco

I believe this is a double definition.

'the author umberto' is the first definition.
(Italian author Umberto Eco, 1932-2016)

'green?' is the second definition.
(abbreviation for ecological)

(Other definitions for eco that I've seen before include "Umberto --, Italian writer" , "Umberto - - , novelist" , "Concerned with the environment" , "Umberto -, Italian author (The Name of the Rose)" , "Environmental group" .)

I've seen this clue in The Times.
