I chuckled the first time I heard that a Ring without a multiplicative identity (Ring without the i) is called a Rng (pronounced wrong). According to Wikipedia, it's pronounced rung.

How is Rng pronounced in research/academia?

I've always heard it said "rung" since that is close to a phonetic attempt.

But really, in most serious stuff, I think it's preferred to say "in this paper, rings are not assumed to have identity."

You might also enjoy knowing that there is a similar thing done for semirings, that is, a structure like a ring, but the requirement for additive inverses is omitted. Some people call them rigs since they are missing negatives.
