борис

I found a list of russian names on a website with a bunch of nicknames. I just chose борис for this example, because it's a common russian name. My question is; Who would call them by each of the names?

Would борис be like a professional name that strangers would call him?

Who would call him боря?

Who would call him боренька?

Who would call him борька?

I guess what I'm looking for is who would call him by these different names, and in what situations.

Thanks

Борис is the usual address, formal also.
Боря is the usual diminutive, widespread.
Боренька is the pet name used by very close people.
Борька is a bit rollicking, used by all friends of his. :wink:
