Some letters become quiet when pronounced in English after their spellings were determined. Silent letters, for example, aid in the differentiation of homophones (words with the same sound but distinct spellings and meanings) in writing. You can tell the difference between two, to, and too thanks to silent letters!
When it appears before 't' or after'm,' the letter 'b' can function as a silent letter. The 'b' acts as a silent letter in words like 'comb,' 'tomb,' 'bomb,' 'debt,' and 'doubt,' among others. Of course, there are exceptions to any rule, and the term 'get' is no exception.
One good way to know if a letter is silent is to memorize the common patterns or rules in a specific language. For example, in English, GH is usually silent (as in “right,” “eight,” or “neighbor”). So is the K in KN (see “knee,” “know,” “knock”).
Showing pupils that those letters aren't always silent is one method to introduce them to them. They're spoken in similar tones. The b, for example, is silent in debt but audible in debit. The g in sign is similarly quiet, but it is not in signal.
Some letters become quiet when pronounced in English after their spellings were determined. Experts believe that around 60% of English words have silent letters today. If you just utilised the letters that made sounds, the word "knife" could be spelt "nif."
