What is written on Harry hand?

The most famous thing written on Harry Potter's hand is the "Dark Mark", a symbol of Lord Voldemort and his Death Eaters. It was forcibly branded onto Harry's arm by Bellatrix Lestrange in the Department of Mysteries during the events of "Order of the Phoenix."

However, there are other things written on Harry's hand throughout the series:

* "I must not tell lies" - This is written on the back of Harry's hand in "Sorcerer's Stone" by Professor Flitwick, a magical inscription that serves as a reminder to be truthful.

* "The Boy Who Lived" - This inscription is often written on Harry's hand by fans or in fanfiction as a testament to his status as the one who survived Voldemort's Killing Curse.

Please note that while these are common interpretations, they are not explicitly stated in the books.
