unu

Unu is a term with multiple senses across languages and as an acronym. In Esperanto, unu is the cardinal number for one. It is used in counting and in compounds with other numbers, for example unu, du, tri, and can appear in ordinal or emphatic contexts when forming larger numerals. In Romanian, unu is also the numeral for one and can function as a pronoun in phrases such as unu dintre noi, meaning one of us, or be used in counting.

Beyond its use as a numeral, unu appears as a root in various word formations in different languages, with the precise meaning depending on context. The capitalization UNU is commonly used as an acronym for United Nations University, an international academic institution established by the United Nations. The UNU operates under the umbrella of the UN system, with its headquarters in Tokyo and campuses and programs worldwide. It focuses on research, policy analysis, and capacity-building in areas related to sustainable development, science, and technology.

In short, unu has linguistic significance as the number one in some languages, and as a modern acronym, UNU designates a United Nations-backed university. The exact interpretation depends on the linguistic or organizational context in which it appears.
