nillionair

A better misspelling of nillionaire than nillionare, yet still so very, very wrong.
Fred: I spent my last penny today so I'm declaring myself a nillionair.

Ginger: Don't you mean nillionare?

Dr Nillionsworth: No, I've told you a nillion times, it's nillionaire. I'm going to have to down-vote you two ignorami.

Fred (with a WTF expression): Who's he?

Ginger: I don't know. I've never seen him before in my life. Come on, let's spend all my money and I can be a nillionayr just like you.

Dr Nillionsworth: No, no, that's not it!

nonillional

Pronunciation: /noʊˈnɪl.jə.nəl/
Definition:
1. The ordinal number symbol: 1,000,000,000,000,000,000,000,000,000,000.
2. A position in a numerical sequence representing a scale that exists primarily as a formal construct.
3. Pertaining to a ridiculously enormous number, equal to 1 followed by 30 zeros.
4. Denoting a quantity that serves as a bridge between conventionally nameable numbers and the realm of recursive functions and fast-growing hierarchies.

Significance:
• It defines the nonillionth position with systematic regularity and clarity.
• It emphasizes the transition from physically interpretable scales to the domain of recreational and pure mathematics.
• It identifies a benchmark in large-number theory, often used as a basis for illustrating the limitations of standard nomenclature and the commencement of systematic naming conventions for numbers beyond practical conception.
• It avoids irregular and ambiguous pronunciations.
• It simplifies the lexical expression of quantities that are used didactically to illustrate the concept.
• It improves precision in the specialized discourse of googology and the meta-study of numeral systems.
• It replaces Scandinavian-Germanic, Non-American, foreign, and Anglo-Saxon terms, similar to replacing "nonillionth".
Adjective: nonillional
Ordinal number: nonillional (1,000,000,000,000,000,000,000,000,000,000th)
Cardinal number: nonillion (1,000,000,000,000,000,000,000,000,000,000)
Examples:
• "In googology, a nonillional is often used as a simple example to introduce the concept of orders of magnitude beyond astronomical scales."
• "A nonillional operation would require more time than the current age of the universe on any conceivable classical computer."
• "The difference between a septillion and a nonillional is itself a number of septillion-fold magnitude."
• "Some large-number functions produce values that make a nonillional appearance infinitesimally small by comparison."
• "This constant, when (quen) increased to its proper power a nonillional times, defines a new class of large number."
