The reason why Lear is true to the ‘tragic hero’ trope is because he fulfills all of the five characteristics. His error of judgement is his inability to judge sincerity within his daughters when he divides his land. This is his hamartia, he would rather be lied to if it meant feeding his ego. His intentions when splitting up his land are good intentions however his error of judgement gets the better of him which has a snowball effect leading to his characters fall. His hamartia leads directly into his peripetia.

His reversal of fortune is when he is kicked out of his castle and is forced to survive in the wild. Here we see how all of actions have lead to him being banished from his own kingdom, then time after another we see him break and reconnect with the world, only to break again. He used to rule England, now we see him completely naked. He was once at the top of the great chain of being, now he’s completely fallen off and is at the bottom, his flower crown symbolises how he percieves himself as less valuable than plant life (which is at the very bottom of the great chain). He’s gone from riches to rags, a complete reversal of fortune.

Lear’s recognition, that helps him fit the tragic hero role, occurs right as Cordelia has died. His most treasured and lovely daughter has fallen at the expense of his own actions and now those actions are confronting him directly. It’s not until he’s lost everything that’s truly important to him, that he can realise how much it meant to him. It is truly painful to see what he has done to Cordelia.
Howl, howl, howl, howl! O, you are men of stones:
Had I your tongues and eyes, I’ld use them so
That heaven’s vault should crack. She’s gone for ever! He say’s howl because he is howling in pain at his grief over his lost daughter.

An example of Lear’s hamartia is also his hubris, which is his excessive pride. This is quite a defining fatal flaw
