twoentry

Twoentry is a term used in various disciplines to denote a system or object that involves two entries, components, or endpoints. It is a neologism rather than a formally standardized term, and its precise meaning depends on context.

In accounting and bookkeeping, two-entry systems are described as simplified ledgers that record each transaction in two places, often as a pedagogical contrast to the more common double-entry system. In contemporary professional practice, double-entry (two entries per transaction) is standard; two-entry references are usually historical or educational.

In information technology and data modeling, twoentry may describe a minimal record consisting of two fields, typically a key and a value. Such usage is common in introductory examples of maps or associative arrays, illustrating the simplest form of a two-field data item.

In publishing, libraries, or bibliographic contexts, twoentry can refer to paired records linked to represent related concepts, such as a main entry and a cross-reference. This use is informal and varies by cataloging tradition.

Because the term is not universally defined, precision is achieved by using more established terms in each domain, such as single-entry, double-entry, or key-value pair. Twoentry functions as a useful shorthand in discussions of dual-entry concepts but should be clarified in formal documentation.
