20 Words That Start with a Silent 'K'

Have you ever noticed how some English words begin with a K that you never actually hear? It’s one of those quirks that makes English spelling both charming and confusing. The silent K is a classic example of how pronunciation and spelling don’t always go hand in hand.

There are actually quite a few common words that start with a silent K. A well-known list includes 20 of them — starting with know, where the 'K' is completely quiet. Then come knee, knot, knit, knock, kneel, knelt, and knack. These are just the beginning.

Other examples include knife, knob, knuckle, knowledge, knoll, knapsack, and knight. Try saying them out loud — no “kuh” sound at the start. That’s the silent K at work.

This pattern dates back to Old English and Norse roots. Over time, the 'K' sound faded from speech, but the spelling stuck around. It’s like a fossil in the language — a reminder of how words used to be said centuries ago.

Interestingly, the silent K only appears before an N at the beginning of words. After all, we *do* say the 'K' in words like “kangaroo” or “kitchen.” So it’s not that the letter is always silent — just in specific combinations.

Whether you’re studying for a spelling test or just curious about language oddities, these 20 words offer a fun glimpse into English’s unpredictable nature. Next time you write knight, remember — that silent K may be quiet, but it’s full of history.
