Origin: Spanish or Yiddish רֵײנָא
Meaning: “queen” or “pure”
The name can either be from the Spanish word for queen or comes from the Yiddish word, rein, meaning “clean; pure.”
In the Spanish-speaking world, the name has been around since Medieval times and was often used as a Regina equivalent.
Among European Jews, the name was used as a Yiddish form of Katherine, sometimes transliterated as Rayna (English), Reina/Raina (German) or Rejna (Polish).
Rayna is coincidentally a Bulgarian female form of Rayno, believed to be derived from Radko, which itself is derived from the Slavic element, rad (care).
It can also likewise be the Latvian word for the Rhine river, and is the name of two different places, one in Estonia and the other in Spain. It is the name of a type of grape used to make red wine.
Another form is the Medieval French, Reine.
Currently, Reina is the 977th most popular female name in the United States (2010), while Rayna ranked in at 899 (2010).
The designated name-day in Estonia is September 7.
