Lithuania [SEP] Etymology
The first known record of the name of Lithuania () is in a 9 March 1009 story of Saint Bruno in the Quedlinburg Chronicle. The Chronicle recorded a Latinized form of the name Lietuva: "Litua" (pronounced ). Due to the lack of reliable evidence, the true meaning of the name is unknown. Nowadays, scholars still debate the meaning of the word and there are a few plausible versions. Since "Lietuva" has a suffix (-"uva"), the original word should have no suffix. A likely candidate is "Lietā". Because many Baltic ethnonyms originated from hydronyms, linguists have searched for its origin among local hydronyms.
