Why are silent letters used in some words of English language?
That's interesting. How do we know when a letter is silent or not in a word?
Sometimes it can be difficult to know whether a letter in a word is silent or not, as the rules for silent letters are not always consistent. However, there are some general patterns to look out for, such as the fact that the letter "e" is often silent at the end of a word, especially after a consonant. Another pattern is that the letter "h" is often silent when it comes before the letter "n", as in the word "honest".
