Üli

The name Üli is a diminutive form of names beginning with the Germanic element *ūl- or *ōþel-, meaning 'wealth' or 'heritage'. It is particularly associated with the name Ulrich, which combines *ōþel- with *rīk- meaning 'power' or 'ruler'. While Ulrich has a long history in Germanic-speaking regions, Üli emerged as a more informal and affectionate short form.

Its usage is primarily found in German-speaking countries, especially Switzerland and southern Germany, where diminutives are common. It retains a traditional feel but is less formal than its longer counterparts. The name has not seen widespread international adoption, remaining largely within its cultural and linguistic origins.
