Why does sign have silent G?

Answer 1

"Sign" has a silent G because there's a GN bond at the end of the word. The reason for the silent G here is to make the I sounds long. The I or O can sometimes be long when they come before 2 consonants and the GN bond is an example of making a long I sound.

Answer 2

The "g" in the word "sign" is silent because it follows the letter "i." In English, when "g" follows "i," it is usually silent. This pattern is seen in many other words as well, such as "gnat," "gnome," and "gnaw."
