The Prose Edda, also known as the Younger Edda, Snorri's Edda () or, historically, simply as Edda, is an Old Norse textbook written in Iceland during the early 13th century. The work is often considered to have been to some extent written, or at least compiled, by the Icelandic scholar, lawspeaker, and historian Snorri Sturluson 1220. It is considered the fullest and most detailed source for modern knowledge of Norse mythology, the body of myths of the North Germanic peoples, and draws from a wide variety of sources, including versions of poems that survive into today in a collection known as the Poetic Edda.
The Prose Edda consists of four sections: The Prologue, a euhemerized account of the Norse gods; Gylfaginning, which provides a question and answer format that details aspects of Norse mythology (consisting of approximately 20,000 words), Skáldskaparmál, which continues this format before providing lists of kennings and heiti (approximately 50,000 words); and Háttatal, which discusses the composition of traditional skaldic poetry (approximately 20,000 words).
Dating from 1300 to 1600, seven manuscripts of the Prose Edda differ from one another in notable ways, which provides researchers with independent textual value for analysis. The Prose Edda appears to have functioned similarly to a contemporary textbook, with the goal of assisting Icelandic poets and readers in understanding the subtleties of alliterative verse, and to grasp the meaning behind the many kennings used in skaldic poetry.
Originally known to scholars simply as Edda, the Prose Edda gained its contemporary name in order to differentiate it from the Poetic Edda. Early scholars of the Prose Edda suspected that there once existed a collection of entire poems, a theory confirmed with the rediscovery of manuscripts of the Poetic Edda.
Naming
The etymology of "Edda" remains uncertain; there are many hypotheses about its meaning and development, yet little agreement. Some argue that the word derives from the name of Oddi, a town in the south of Iceland where Snorri was raised. Edda could therefore mean "book of Oddi." However, this assumption is generally rejected. Anthony Faulkes in his English translation of the Prose Edda comments that this is "unlikely, both in terms of linguistics and history" since Snorri was no longer living at Oddi when he composed his work.
Another connection was made with the word óðr, which means 'poetry or inspiration' in Old Norse.
Edda also means 'great-grandparent', a word that appears in Skáldskaparmál, which occurs as the name of a figure in the eddic poem Rigsthula and in other medieval texts.
A final hypothesis is derived from the Latin edo, meaning "I write". It relies on the fact that the word "kredda" (meaning "belief") is certified and comes from the Latin "credo", meaning 'I believe'. Edda in this case could be translated as "Poetic Art". This is the meaning that the word was then given in the medieval period. (therefore before the drafting of the Edda of Snorri), and so the Poetic Edda is also known as the Elder Edda.
Manuscripts
Seven manuscripts of the Prose Edda have survived into the present day: Six copies from the medieval period and another dating to the 1600s. No one manuscript is complete, and each has variations. In addition to three fragments, the four main manuscripts are Codex Regius, Codex Wormianus, Codex Trajectinus, and the Codex Upsaliensis:

The other three manuscripts are AM 748; AM 757 a 4to; and AM 738 II 4to, AM le ß fol. Although some scholars have doubted whether a sound stemma of the manuscripts can be created, due to the possibility of scribes drawing on multiple exemplars or from memory, recent work has found that the main sources of each manuscript can be fairly readily ascertained. The Prose Edda remained fairly unknown outside of Iceland until the publication of the Edda Islandorum in 1665.
Authorship
The text is generally considered to have been written or at least compiled by Snorri Sturluson. This identification is largely based on the following paragraph from a portion of Codex Upsaliensis, an early 14th-century manuscript containing the Edda:
