Which regions language was least influenced by the indo-european migrations?

The regions whose languages were least influenced by the Indo-European migrations are those located in Southeast Asia, the Americas, Sub-Saharan Africa, and Oceania.

Here's a breakdown:

* Southeast Asia: Languages like Thai, Vietnamese, and Khmer belong to the Austroasiatic, Tai-Kadai, and Austronesian language families, respectively, which predate the arrival of Indo-European languages.

* The Americas: Native American languages, like Navajo, Cherokee, and Quechua, are unrelated to Indo-European languages and have their own rich history and diversity.

* Sub-Saharan Africa: The majority of languages in this region belong to various language families, including Niger-Congo, Afro-Asiatic, and Nilo-Saharan. These families are independent of Indo-European, and their origins precede the spread of Indo-European languages.

* Oceania: The languages of Oceania, including Polynesian, Micronesian, and Melanesian, belong to the Austronesian family and were established before the Indo-European expansion.

It's important to remember that there are exceptions and complexities within these regions. For instance, some languages in these regions might show minor influences from Indo-European languages due to trade, colonialism, or other historical interactions. However, overall, these regions retained their linguistic diversity and were less significantly impacted by the Indo-European migrations compared to Europe, Central Asia, and parts of the Middle East.
