talnagrunn

Talnagrunn is a term used in linguistic studies to denote the foundational structure underlying numeral expressions in a language or numeral system. The concept focuses on how number words are built from smaller units and how different base systems organize these units. As a theoretical construct, talnagrunn helps linguists compare numeral formation across languages and model how speakers mentally structure large numbers.

Origin and meaning: the word combines Norwegian roots tal, meaning "number," and grunn, meaning "ground" or "base."

Within talnagrunn, numerals are analyzed as hierarchical decompositions. Core components include base units (one through nine), tens, hundreds, and higher scales, together with language-specific morphosyntactic rules for combining them. The framework accommodates both base-10 systems and non-decimal systems by describing the recursive rules that connect small units to larger ones, and it addresses phenomena such as multiplicative construction, place value, and irregular forms in the teens.

It is used in typological descriptions of numeral systems, in computational parsing of numbers in natural language processing, and in educational contexts to explain how different languages encode quantities. Researchers may employ talnagrunn to illustrate how languages differ in the order of terms (for example, "twenty-one" versus "one-and-twenty") and in the treatment of thousands and beyond.
