The silent K in KN- words was not always silent — in Old English and Old Norse, it was pronounced. "Knight" was said like "k-niht." The K went silent around the 17th century, but the spelling was kept, giving English one of its most famous spelling quirks.

Some popular K-words include KABAKA, KABUL, KAISERLI, KAJI, KALEVALA, KAME, KANNADA, KARACHI. Browse the full list above organized by word length, with game scores for each word.

K starts roughly 1.5% of English words, far fewer than its sound frequency would suggest — because the K sound is often spelled with C or CK. True K-words tend to be Old Norse or Germanic imports: KNIFE, KNIGHT, KNEEL (with a silent K), plus Yiddish contributions like KIBBUTZ and KLUTZ.

The KN- cluster words are a hidden asset: KNACK, KNAVE, KNEEL, KNIT, KNOCK, KNOT, KNOW. The K is silent in all of them, but they are valid words that opponents may overlook. Short K-words (KEY, KID, KIT) are reliable on small grids. KI, KA, and KO are valid in some dictionaries and worth checking your game ruleset.
