Question: What is the Old Icelandic name of the jutish chieftain on whom Hamlet was based?
Context: Linguistic purism in Icelandic is a sociolinguistic phenomenon with the aim of substituting loanwords with the creation of new words from Old Icelandic and Old Norse roots and preventing new loanwords from entering the language.  In Iceland, linguistic purism is archaising, trying to resuscitate the language of a golden age of Icelandic literature.  The effort began in the early 19th century, at the dawn of the Icelandic national movement, aiming at replacing older loanwords, especially from Danish, and it continues today, targeting English words.  It is widely upheld in Iceland and it is the dominant language ideology.  It is fully supported by the Icelandic government through the Árni Magnússon Institute for Icelandic Studies, the Icelandic Language Council, the Icelandic Language Fund and an Icelandic Language Day. There are two sites in Denmark presented as Hamlet's Grave ("Hamlets Grav"), the burial site of Amleth ("Amlethus, Amlodi, Amblett"), the Jutish chieftain of historical legend on whom Hamlet, the hero of Shakespeare's tragedy was based; one is in the grounds of Marienlyst Castle in Helsingør, the other is a Bronze Age tumulus in Ammelhede, Randers Municipality, Jutland. Feng was a legendary Jutish chieftain and the prototype for William Shakespeare's King Claudius.  He appears in "Chronicon Lethrense" and in Saxo Grammaticus' "Gesta Danorum" (book 3). Wihtgils ("fl. " 5th century) was a semi-legendary Jutish chieftain who, according to the "Anglo-Saxon Chronicle", was the father of Hengest and Horsa: Þorgnýr the Lawspeaker (Old Icelandic: "Þorgnýr lögmaðr", Swedish: "Torgny Lagman") is the name of one of at least three generations of lawspeakers by the name "Þorgnýr", who appear in the "Heimskringla" by the Icelandic scholar and chieftain Snorri Sturluson, and in the less known "Styrbjarnar þáttr Svíakappa" and "Hróa þáttr heimska".  They were the lawspeakers of Tiundaland, and all lawspeakers in the Swedish kingdom were their subordinates. King Claudius is a fictional character and the primary antagonist of William Shakespeare's tragedy "Hamlet".  He is the brother to King Hamlet, second husband to Gertrude and uncle and later stepfather to Hamlet.  He obtained the throne of Denmark by murdering his own brother with poison and then marrying the late king's widow.  He is loosely based on the Jutish chieftain Feng who appears in "Chronicon Lethrense" and in Saxo Grammaticus' "Gesta Danorum".  There had never been an actual Danish King of that name. Horwendill was a legendary Jutish chieftain, who is the prototype for William Shakespeare's King Hamlet, Prince Hamlet's father.  He appears in "Chronicon Lethrense" and in Saxo Grammaticus' "Gesta Danorum" (book 3). Amleth (Latinized "Amlethus", Old Icelandic "Amlóði") is a figure in a medieval Scandinavian legend, the direct predecessor of the character of Prince Hamlet, the hero of William Shakespeare's tragedy "Hamlet, Prince of Denmark". "See Witta, son of Wecta for the mythological Jutish chieftain." Witta son of Wecta is mentioned as a Jutish chieftain in the 449 entry of the "Anglo-Saxon Chronicle" as the father of Wihtgils and the grandfather of Hengest and Horsa.  He also appears in the same role in Henry of Huntingdon's "Historia Anglorum".  He is most probably mythological, but as a historical person he would have been born around 400 AD.
Answer: "Amlóði"
