What do the letters "I N R I" on Jesus'cross mean?

The letters "INRI" are initials for Latin title that Pontius Pilate had written over the
head of Jesus Christ on the cross (John 19:19).Latin was the official language of
the Roman Empire.The words were  "Iesvs Nazarennvs Rex Ivdaeorvm.)"Latin uses"I"
instead of the English "J" and "V" instead of "U" (i.e., Jesus Nazarenus Rex Judaeorum).
It read:Jesus the Nazarean,the King of Jews,as it was the custom to place  sign stating
the offense on the cross in Latin,Greek,and Hebrew.The Early Church adopted the first
letters of each word of  inscription "INRI" as a symbol. Throughout the centuries INRI
has appeared in many paintings of the crucifixion.
