Silence is one of the great arts of conversation
Silent letters are a fascinating feature of English words, and they often confuse learners because they're written but not pronounced. Mispronouncing English words leads to several problems, especially in communication and professional settings. Here’s a brief overview of the key detriments and a breakdown of why silent letters exist, their origin, and common examples.
Mispronunciation causes confusion or misinterpretation. For example, saying “dessert” instead of “desert” (stress difference) completely changes the meaning.
Listeners may struggle to follow or understand your message.
Frequent pronunciation mistakes make speakers feel self-conscious or anxious about speaking in public or social situations.
In job interviews, business meetings, or presentations, poor pronunciation may be perceived as a lack of language proficiency, even if your grammar or vocabulary is strong.
While accents are natural and acceptable, consistent mispronunciations (especially of common or basic words) are sometimes unfairly judged, affecting credibility or first impressions. Improving your pronunciation doesn’t mean eliminating your accent; it means making yourself clear and understandable.
Why Silent Letters Exist in English
English spelling was standardized long after the pronunciation of many words had changed. As a result, letters that used to be pronounced are still written, even though they're now silent.
English borrowed many words from Latin, Greek, French, and other languages. When borrowed, the original spelling was often preserved, even if English speakers didn't pronounce all the letters.
The Great Vowel Shift (between 1400 and 1700) changed how vowels were pronounced in English. Many consonants around them became silent, but spellings stayed the same.
When dictionaries started becoming popular (notably Samuel Johnson’s dictionary in 1755), spelling was frozen even though spoken language kept evolving. Some silent letters were added to reflect the word’s Latin or Greek origin, even if they weren't pronounced (for example, the letter “b” in the word debt was added to reflect the Latin word debitum).
Origins of English Silent Letters
Old English ~ Many silent letters (like the “k” in “knight”) were pronounced in Old English.
Norman French ~ After the Norman Conquest (1066), French spelling conventions influenced English.
Greek and Latin ~ Scientific and academic vocabulary often includes silent letters because of roots from classical languages.
Printing Practices ~ Printers sometimes inserted letters to justify lines or make words look more classical or scholarly.
The 5 most common English words with silent letters are ...
knife - the k is silent
island - the s is silent
doubt - the b is silent
hour - the h is silent
listen - the t is silent
Here is a list of 400 English words with silent letters.
One of the reasons English pronunciation is challenging is that there are no rules that will help you learn the pronunciation of words in English that have silent letters; you just have to remember them.
