When you say that the handwriting or writing is on the wall, what you mean is that something disastrous or bad is going to happen.
* When the team lost in the first round of the playoffs, the writing was on the wall for the coach. * Prabhakar saw the handwriting on the wall when the company fired two more people.
The expression “handwriting on the wall” comes from the Bible. The King of Babylon, Belshazzar, sees a hand mysteriously appear and write a message on a wall. Being unable to decipher the message, he summons Daniel. The wise man tells Belshazzar that the message is a warning from God that he will soon be overthrown and his kingdom destroyed.
