Are there any words for king derived from Caesar besides in Russian and German?

Durn ya, jtd! I was trying to grab the 20,000th post under Q&A, but you beat me to it! I am in awe of your swift fingers!

I think you probably went into the reply screen just as I went out, because I went into miscellany before I saw the new post mark on Q&A.

Kaisar is the Indonesian for emperor, presumably from Dutch.

Bingley

The form Kaisar seems to be in several eastern languages. There's a British medal called the Kaisar-I-Hind Medal, which presumably means Emperor of India, but I can't say exactly what language. The -i- connective is the Dari (Afghan) version of the Persian -e-. I don't know whether it was borrowed into any Indian languages, such as Urdu. This construction is Persian, and is not native to true Indian languages.
