Question

Who were the Proto Indo-Europeans?

Answer 1

They were people from Central Asia who are believed to be the source of many modern languages in Europe and Asia.

One thing I have wondered about for a long time:

In all major European languages that I am aware of, except one, the words for "no" are similar: no, non, nein, nyet ne, nei, etc.

BUT, in Greek, "nai" means "yes"!

Why?

Comments

We have ‘na’ as a basic way of saying ‘no’ in Welsh.

Sometimes words get switched

Amma (similar terms) = Mother in Dravidian languages

Appa(similar terms) = Father in Dravidian languages

But it got switched in Tulu language - https://www.quora.com/What-is-the-explanation-behind-the-semantic-reversal-of-the-terms-for-father-and-mother-in-Tulu-appe-being-mother-and-amme-being-father

Remarkable switch in Tulu.
