Post interesting things about etymology

In Turkish the father-in-law or mother-in-law of one's child is called dünür which derives from tengri (like tenger, denger, dengir, tanrı etc) (spelled with nasal n)

krgyz and uygurs call tengri kuday (might be derived persian hüda), they also call co-in-laws kuday.

I always thought it was interesting.

Also the word thor or donar might be derived from tengri
