Mateo Kovacic is a two-part proper noun combined name commonly used to refer to a Croatian football player. In this context, treated as a full, non-declinable label; it can function as a compound name with cultural origin notes. The phrase is typically used in sports journalism, discussions of players, and fan commentary, and it should be pronounced as a cohesive unit rather than acronymized. It may also appear with diacritics in some languages, but in English contexts it is spoken plainly.
