What are the 5 major branches of Indo European languages?

It's not quite accurate to say there are "5 major branches" of Indo-European languages. While there are several primary branches, it's more accurate to say there are 10 major branches of Indo-European languages. Here are the most widely accepted ones:

1. Indo-Iranian: Includes languages like Hindi, Urdu, Bengali, Persian, and Pashto.

2. Balto-Slavic: Includes languages like Russian, Polish, Ukrainian, Lithuanian, Latvian, and Slovene.

3. Germanic: Includes languages like English, German, Dutch, Swedish, Norwegian, and Icelandic.

4. Italic: Includes languages like Latin (ancestor of Romance languages), Spanish, Portuguese, French, Italian, and Romanian.

5. Celtic: Includes languages like Irish, Scottish Gaelic, Welsh, Breton, and Manx.

6. Greek: Includes modern Greek, and its ancestors (Ancient Greek, Koine Greek).

7. Armenian: Includes modern Armenian.

8. Albanian: Includes Albanian and its dialects.

9. Tocharian: An extinct group of languages once spoken in Central Asia.

10. Anatolian: An extinct group of languages spoken in Anatolia (modern Turkey), including Hittite.

Important Note: The exact number and classification of Indo-European branches can be debated among linguists, and some might argue for slightly different classifications or include additional branches.
