Read the play.  Is it about nominalism vs. realism?  Is it about fathers & sons?  Is it Shakespeare's love letter to his own son, Hamnet?

"Hament died when he was eleven years old, in August 1596, due to unknown causes., It’s thought that he possibly died from the bubonic plague that killed around one-third of all children below the age of twelve in Elizabethan England."

The name Hamlet occurs in the form Amleth in a 13th-century book of Danish History written by Saxo Grammaticus, popularised by François de Belleforest as L'histoire tragique d'Hamlet, and appearing in the English translation as "Hamblet". The story of Amleth is assumed to originate in Old Norse or Icelandic poetry from several centuries earlier. Saxo has it as Amlethus, the Latin form of the old Jutish Amlethæ. In terms of etymology the Old Icelandic name Amlóði comes from the Icelandic noun amlóði, meaning ‘fool,’ suggestive of the way that Hamlet acts in the play. Later these names were incorporated into Irish as Amlodhe. As phonetic laws took their course the name’s spelling changed eventually leaving it as Amlaidhe. This Irish name was given to a hero in a common folk story. The root of this name is ‘furious, raging, wild’.
