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. With the accession of
Indo-Uralic languages resemblances seems uncomfortably high. The strongly divergent sound systems of Proto-Indo-European and Proto-Uralic are an aggravating factor both in the morphological and the lexical realm, making it additionally difficult to judge resemblances and interpret them as either borrowings, possible cognates or chance resemblances. A second type of evidence advanced in favor of an Indo-Uralic family is lexical. Numerous words in Indo-European and Uralic resemble each other (see list below). The problem is to weed out cognates due to borrowing. Uralic languages have been in contact with a succession of Indo-European languages for millennia. As a result, many words have been
