English has many silent letters that confuse learners. The letter appears in the spelling but doesn't make a sound when you say the word.
The B Silent Letter Rule
B is silent after M at the end of words (climb, dumb, numb) and before T (debt, doubt).
The K Silent Letter Rule
K is silent before N at the beginning of a word. This is one of the most common silent letter patterns in English.
The W and G Silent Letter Rules
W is silent before R at the beginning (write, wrong, wrap). G is silent before N at the beginning (gnome, gnat, gnaw).
The H Silent Letter Rule
H is silent at the beginning of many words (honest, hour, honor) and in certain combinations.
