thúsundrþúsund

Thúsundrþúsund is a coined numeral used in speculative linguistics and fictional world-building. It is not an established term in real-world numeral systems. In the fictional contexts where it appears, thúsundrþúsund denotes a quantity formed by multiplying a thousand by another thousand, yielding one million. The term is sometimes employed to illustrate how multiplicative compound numerals could be constructed in a language that resembles Nordic or Germanic traditions.

Etymology and morphology: The form combines the base word for thousand (thúsund) with a linking element (r) and a second instance of thousand, producing thúsundrþúsund. In ASCII transliteration the form appears as thúsundrþúsund. Such compounds are common in conlangs as a way to express large scales by stacking base numerals, rather than using a borrowed or standardized word for million.

Usage and interpretation: In fictional grammars, thúsundrþúsund is defined as 1,000,000; larger magnitudes can be built by repetition or multiplication (e.g., two thúsundrþúsund for two million). Authors may use the term in fantasy economies, legendary chronicles, or educational conworlds to demonstrate multiplicative syntax without resorting to real-language borrowings. Because it is a constructed term, its exact pronunciation and spelling vary by work and orthography.
