Language repeats on broadcast (9)

I believe the answer is:

esperanto

'language' is the definition.
(Esperanto is an example)

'repeats on broadcast' is the wordplay.
'broadcast' is an anagram indicator.
'repeats'+'on'='repeatson'
'repeatson' is an anagram of 'ESPERANTO'.

(Other definitions for esperanto that I've seen before include "Artificial speech-form" , "Personate in artificial language" , "Universal language" , "Dr Zamenhof's language" , "words, set up artificially?" .)

I've seen this clue in The Telegraph.
