Most languages of Europe belong to the Indo-European language family. Out of a total European population of 744 million as of 2018, some 94% are native speakers of an Indo-European language. Within Indo-European, the three largest phyla in Europe are Romance, Germanic, and Slavic; they have more than 200 million speakers each and together account for close to 90% of Europeans. Smaller phyla of Indo-European found in Europe include Hellenic (Greek, 13 million), Baltic ( 7 million), Albanian ( 5 million), Celtic ( 4 million), and Armenian ( 4 million); Indo-Aryan, though a large subfamily of Indo-European, has a relatively small number of speakers in Europe (Romani, 1.5 million).
Of the approximately 45 million Europeans speaking non-Indo-European languages, most speak languages within either the Uralic or Turkic families. Still smaller groups — such as Basque (language isolate), Semitic languages (Maltese, 0.5 million), and various languages of the Caucasus — account for less than 1% of the European population among them. Immigration has added sizeable communities of speakers of African and Asian languages, amounting to about 4% of the population, with Arabic being the most widely spoken of them.
Five languages have more than 50 million native speakers in Europe: Russian, French, Italian, German, and English. Russian is the most-spoken native language in Europe, and English has the largest number of speakers in total, including some 200 million speakers of English as a second or foreign language.

Indo-European languages and List of Indo-European languages
The Indo-European language family is descended from Proto-Indo-European, which is believed to have been spoken thousands of years ago. Early speakers of Indo-European daughter languages most likely expanded into Europe with the incipient Bronze Age, around 4,000 years ago (Bell-Beaker culture).
The Germanic languages make up the predominant language family in Western, Northern and Central Europe.
