What is silent letter in a word first?

A silent letter is a letter in a word that is not pronounced. It's like a ghost letter, there but not heard!

Here's an example:

* Knight: The "k" is silent. You only pronounce "night."

Why do we have silent letters?

* Historical Reasons: Languages change over time. Sometimes a sound that was once pronounced disappears, but the letter remains.

* Spelling Conventions: Sometimes, words are spelled in a way that reflects their origin, even if the pronunciation has changed.
