Name origin.

I previously made a thread about something similar, but just about where your name is derived from, not exact details. Well, this thread is to discuss every single distinct and exact node of your name's etymology.
I made this animation to explain mine, it is Old Norse.

From Old Norse Eiríkr, this changed into Old West Norse Eiríkur(And ultimately into Eirík/Eirik), and Old East Norse Erik. Marauding Scandinavian invaders like the Danes and Normans brought the name to England with them, but it dissipated until a surprise revival in the 18th century... Scandinavian settlers likewise carried the name with them to the Americas, upon which time it was first Anglicized into "Eric", which is now regarded the "standard" spelling, and the usually most preferred one.

Oh my. That's a real lot about the history and origin of your name. I wish I could say that much about mine.

But I don't know much about it's history and origin. In fact, I know nearly nothing about the history and origin of "Anirban", my first name. I only know two things about it. One, it's a Bengali name, and a really uncommon one at that. Two, the meaning of my name is "ever enlightened". That's all.

But one question - how do you know that much about the history and origin of your name, Eric (or Erik)?

It was a fun project we did in High School, to present the origins of our first names. Mine was weird in that it was spelt with a c instead of a k at the end, so I had to do more research...
Anyway, I think I have an idea on the origins of your name.
It probably comes from,
"A-"(akin to the un- prefix in English, as in unbelievable) + "Nirvana"(death)...So, Anirvana probably meant "the undying" in Sanskrit, but it was a common feature of Sanskrit to aspirate the last letter of compound words. Again "A-" can also denote "Always" in Sanskrit, and Nirvana can mean "enlightenment" if you take the Buddhist semantic view, which is also valid in Sanskrit, so yeah, Anirban might most probably derive from that name, and it fits the description accordingly.
Anyway, the "A-"(always) of Sanskrit and "Ei"(always) of Old Norse sound pretty similar...maybe they're cognate(related) prefixes? After all, Old Norse "Ríkr"(ruler, king) is related to Latin "Rex"(king) and Sanskrit "Raja"(king).

Oh my goodness. You are a real scholar. I have no idea about the history and origin of my name. But what you said might be true I really don't know. Looks like I'll have to ask my parents whether they know or not. I hope they do.
