RaDi

Radi is a masculine given name in several South Slavic languages, often used as a standalone name or as a diminutive of longer names such as Radovan, Radomir, Radislav, or Radimir. Etymologically, it derives from the Slavic root rad-, which can carry meanings related to care, joy, or work, depending on the language and context. As a given name, Radi has been particularly common in Bosnia and Herzegovina, Croatia, Montenegro, Serbia, and to a lesser extent in North Macedonia and Slovenia, where it may be given to boys across generations.

Across regional naming traditions, Radi conveys positive associations and is valued for its concise, energetic sound. It may appear in traditional and contemporary records, including official documents, literature, and media. As with many Slavic names, it can function as a nickname for longer forms while also standing alone.

In linguistic usage beyond names, radi- is also a combining form from Latin radius meaning ray or spoke, used in scientific terms such as radiate, radiology, and radiation. This prefix is etymologically distinct from the South Slavic given name Radi, though they share a similar spelling in Latin characters. The term radi is not otherwise common as an independent word in modern English outside its role in these scientific terms or as part of acronyms in specialized contexts.
