Artificial international language (9)

Ross

I believe the answer is:

esperanto

'artificial international language' is the definition.
(I've seen this before)

This is the entire clue.

(Other definitions for esperanto that I've seen before include "No repeats of this artificial language, strangely" , "Ape tenors (anag.)" , "Artificial international language devised in 1887" , "common language" , "composite language" .)

I've seen this clue in the Sydney Morning Herald and The Guardian.
