Rask was born to Niels Hansen Rasch and Birthe Rasmusdatter in the village of Brændekilde near
Odense on the Danish island of
Funen. His father, a
smallholder and tailor, was well-read and had a decently-sized book collection. As a child, Rask's scholastic abilities became apparent, and, in 1801, at the age of thirteen, he was sent to the
Latin school in Odense, now known as the Odense Katedralskole. One of his friends from Latin school, Niels Matthias Petersen (1791–1862), who went on to be the first professor of
Nordic languages at the University of Copenhagen, later remarked that "His short stature, his lively eyes, the ease with which he moved and jumped over tables and benches, his unusual knowledge, and even his quaint peasant dress, attracted the attention of his fellow students". At the Latin school, Rask's interest in
Old Norse and
Icelandic language and
literature was awakened. His teacher, Jochum E. Suhr, loaned him a copy of
Snorri Sturluson's
Heimskringla in Icelandic, and the rector, Ludvig Heiberg, gave him a new translation of the same work as a prize for his diligence. By comparing the original work and the translation, he was able to make an Icelandic vocabulary, cross-referencing the Icelandic words with cognates in
Danish,
Swedish,
German,
Dutch and
English. In addition to Danish and
Latin, Rask studied
Greek,
Hebrew,
French and German at Odense. An interest in
orthography also led Rask to develop his own spelling system for Danish that more closely resembled its pronunciation, and it was at this time that he changed the spelling of his last name from "Rasch" to "Rask". ==University years==
