K is a moderately rare letter in English — less common than most consonants but more productive than J or Q at four letters. This page lists 25 curated K-words tagged by type and difficulty, from everyday vocabulary like keep, kick, kill, kind, king, kiss, knee, knit, knot, and know to specialist entries like kerf, kern, knap, and kohl. The K tile scores 5 points in Scrabble, making every K word a worthwhile play even before premium squares are considered.
K words contain a notable cluster of KN- words — knap, knee, knit, knob, knot, know — where the K is silent in modern English pronunciation. These words reflect an older spelling convention inherited from Germanic languages where the KN combination was once fully pronounced. Knowing that the K is silent helps with spelling but not with Scrabble, where the K tile still scores its full 5 points regardless of pronunciation.
These are the K-words most speakers use and recognise daily. They fall under the Easy difficulty label and are the natural foundation for any K-word vocabulary list.
Several easy K words carry multiple meanings worth knowing. Kind is both an adjective (having a caring nature) and a noun (a category or type — "a kind of bird"). Kite is a toy flown in the wind, a bird of prey, and informal British English for a cheque. Knot is a fastening, a unit of nautical speed (one nautical mile per hour), and a tight cluster of people. King is a ruler, the most important chess piece, and a playing card.
K scores 5 points in Scrabble — the same as Y and one more than F and V. There is only one K tile in a standard set, so drawing it means making the most of every legal K play available.
Kohl scores 11 points (K=5, O=1, H=4, L=1) — a dark eye cosmetic that pairs K with H for a solid score from a rare word. Kerf also scores 11 (K=5, E=1, R=1, F=4) — the slit left by a saw blade, known to carpenters and valid in most Scrabble rulesets. Keep, knob, kelp, and kerb all score 10. Kind, king, and kick score 9. Even the simplest K words — kill, kiss, knit, know — score 8 points, which is above average for a four-letter play without premium squares.
Kerf (a saw cut) and kern (a typographic spacing adjustment; the inner part of a nut) are trades vocabulary that appears in Scrabble word lists and trips up opponents who challenge them. Knap (to shape flint by chipping) is archaeological terminology — valid in most rulesets. Keel (the base of a ship's hull) is medium-difficulty and scores 8 points but is unambiguously valid. Kook (an eccentric person) is informal but legal and scores 10 (K=5, O=1, O=1, K=5 — though this needs a blank for the second K in standard play).
Despite the smaller count, the K list spans craft, culture, cooking, and the body — a wider range than its size suggests.
Five of the 25 words begin with KN- where the K is silent: knap, knee, knit, knob, knot, know. This pattern comes from Old English and Germanic roots — the KN combination was once pronounced with both sounds. By the 17th century, the K before N became silent in speech, but the spelling was retained. French borrowed many of these concepts and spelled them without the K (noeud for knot, nœud; genou for knee). The silent K is one of the most frequently misspelled conventions in English, particularly for younger learners.
Kohl comes from Arabic (kuḥl) and refers to an eye cosmetic used for thousands of years across the Middle East, North Africa, and South Asia — it predates written history in some regions. Kilt comes from a Scandinavian word meaning to tuck up, and became specifically associated with Scottish Highland dress. Kelp is of uncertain origin but appears in Scottish and Northern English dialects. Kiln comes from Latin culina (kitchen or cooking place). English's K words often have non-Germanic roots — the letter was rare in Old English itself and was borrowed or retained from Norse and other sources.
Use the filter bar to narrow by type and difficulty.

This page includes 25 curated four-letter words starting with K. K is less common than most consonants in English but more productive than J or Q at four letters. The list covers nouns, adjectives, and verbs across easy, medium, and hard difficulty levels.
Kohl and kerf both score 11 points (H=4 and F=4 respectively). Keep, knob, kelp, and kerb each score 10. Kind, king, and kick score 9. Even basic K words like kill, know, and knit score 8 — above the average four-letter word value. K scores 5 points on its own, giving a strong floor to every play.
Most standard words on this list are valid in Scrabble, but the official Scrabble word list (TWL for North America, SOWPODS for international play) is the authoritative source. Rare words like kerf, kern, knap, and kohl may or may not be accepted depending on which ruleset you're using.
Easy words are common everyday vocabulary most adult speakers know well. Medium words are less frequent but widely understood. Hard words are uncommon, specialised, or archaic — useful for advanced vocabulary study or competitive Scrabble. Ratings reflect word frequency in standard English usage.
A knot is a deliberate fastening made by tying cord or rope — it can be untied. A kink is an unintentional sharp twist or bend in something that should be straight — a kink in a hose blocks flow, a kink in a plan disrupts it. Knot also means a unit of speed at sea (one nautical mile per hour). Both are four-letter K nouns, but a knot implies intention while a kink implies an unwanted flaw.
