Rayno is a Bulgarian masculine given name, a variant of Radko. Radko itself originates as a diminutive of names beginning with the Slavic element radŭ, meaning "happy, willing". This root is common in Slavic naming traditions, where it forms the basis for many names such as Radek in Czech and Ratko in Serbian. Rayko is a related Bulgarian variant. Because several bearers recorded on Wikipedia are South African, the name appears to be common in South Africa, possibly through Afrikaans or Dutch influence. Notable South African men named Rayno include cricketer Rayno Arendse (born 1978), rugby players Rayno Benjamin (born 1983) and Rayno Gerber (born 1981), strongman Rayno Nel (born 1995), and tennis player Rayno Seegers (born 1952). The prevalence of Northern names in South Africa often stems from the country's diverse colonial history. Feminine forms related to Radko include Radina, Radka, Raina and Rayna in Bulgarian. Meaning: "happy, willing" Origin: Slavic Type: Given name (masculine) Usage: Bulgaria, South Africa
