What is another name for Ethereum?

Could you please clarify for me? I've heard of Ethereum, but I'm wondering if it has any alternative names that people might use to refer to it? Could you tell me what Ethereum is commonly known as, if there is such a thing? I'm trying to broaden my knowledge in the cryptocurrency sphere and it would be helpful to know any aliases or alternate terminologies associated with this particular platform. Thank you for your assistance in this matter.
