teisejärguliste

Teisejärguliste is an Estonian term that appears in various technical texts and does not have a single universally accepted definition. Broadly, it translates as “second-order lists” and is used to refer to lists whose elements themselves form a list, i.e., nested lists, or to lists at the second level in an outline.

In computer science and data processing, teisejärguliste can describe a list of lists (a two-dimensional structure). For example, a variable such as [[1, 2], [3, 4, 5], []] can be described as a teisejärguliste in a loose sense. Such structures are used to represent matrices, graphs (adjacency lists), or grouped items with sublists. They are common in programming languages that allow nested collections and are manipulated through operations on both the outer list and the inner lists.

In document formatting and outlining, teisejärguliste may refer to second-level bullet or numbered lists within a larger list. This use arises in content management and editing when describing hierarchical structures, where each top-level item can contain its own sublist.

In mathematics and logic, second-order concepts are standard, but teisejärguliste is not the conventional term for formal statements. The established term for second-order theory is teise järgu loogika; teisejärguliste is rarely used in formal contexts and is more likely to appear informally or in domain-specific documentation.

Because the term is context-dependent and not standardized, readers should rely on the surrounding text to determine the precise meaning. Related ideas include nested lists, list of lists, and hierarchical lists, as well as second-order logic in formal settings.
