itemitem

Itemitem is a term used in information design and data modeling to describe a composite data element that consists of two sub-items treated as a single unit. The term is a reduplication of the word item and is intended to highlight a pairing or juxtaposition of components. It is not part of a formal standard, and its exact meaning varies by domain.

In data modeling, an itemitem may be represented as a two-element tuple, a small record, or a nested structure where both sub-items are linked or share a common identity. For example, a product bundle could be modeled as an itemitem with two item identifiers (A, B).

In user interface design, an itemitem can refer to a list entry that presents two actionable sub-elements side by side, such as edit and remove controls, or a two-part control that operates on the paired items.

In linguistics and natural language processing, itemitem sometimes appears as an informal label for reduplication or paired tokens, but it is not a widely used technical term.

Because it is informal, itemitem is mainly encountered in tutorials, example datasets, or hypothetical models rather than in formal specifications. Related concepts include pair, tuple, list, and bundle.
