Languages of the European Union languages, Latvian and Lithuanian; the Celtic languages, including Irish; and Greek are also Indo-European. Outside the Indo-European family, Estonian, Finnish, and Hungarian are Uralic languages while Maltese is the only Afroasiatic language with official status in the EU. The Basque language, a language isolate whose roots are unknown, is an official language in some parts of northern Spain, but not an official language of the EU. Most official EU languages are written in the Latin script. The two exceptions are Greek, which is written in the Greek script, and Bulgarian, which is written in Cyrillic script.

This is evidence that the word was borrowed into Finno-Ugric from Indo-Iranian or Indo-Aryan. This borrowing may have occurred in the region north of the Pontic-Caspian steppes around 2100–1800 BC, the approximate floruit of Indo-Iranian (Anthony 2007:371–411). It provides linguistic evidence for the
