Hungarian publication to beam about (6)
I believe the answer is:
magyar
'hungarian' is the definition.
(synonyms)
'publication to beam about' is the wordplay.
'publication' becomes 'mag' (abbreviation for magazine).
'to beam' becomes 'ray' (synonyms).
'about' says the letters should be written backwards.
'ray' reversed gives 'yar'.
'mag'+'yar'='MAGYAR'
(Other definitions for magyar that I've seen before include "Official language of Hungary" , "European" , "Hungarian language" .)
