The Hebrew Letter Kaf / Khaf (כַּף)
The 11th letter of the Hebrew alphabet — with both regular and final forms. Learn its shape, sound, and how to teach it.
About the Letter Kaf
Kaf is the 11th letter of the Hebrew alphabet (Aleph Bet), with a gematria value of 20. Its Hebrew name is כַּף, which means "palm of the hand." Kaf belongs to the group of three dual-sound letters: with a dagesh dot inside (כּ), it is called Kaf and sounds like "k"; without the dagesh, it is called Khaf and sounds like "kh" (the same guttural sound as Het).
Kaf has a final form: Kaf Sofit (ך), used when Kaf appears at the end of a word. Kaf Sofit has the same curved top as regular Kaf but its leg extends far below the baseline. Kaf Sofit is one of the five sofit letters in Hebrew, and recognizing it at word endings is a key milestone in Hebrew reading development.
The Sound of Kaf
How it Sounds
"k" when a dagesh dot appears inside the letter (כּ) — like "king" or "key." "kh" when no dagesh appears (כ/ך) — the same guttural sound as Het, like the "ch" in "Bach." In modern Hebrew, Kaf without a dagesh and Het make the same sound.
In Nikud Texts
In fully pointed texts, the dagesh inside Kaf is clearly shown when the letter makes a "k" sound. For beginners, teach "k" (with dagesh) first, then introduce "kh" (without dagesh). The final form Kaf Sofit (ך) should be introduced alongside regular Kaf so children recognize both shapes.
How to Recognize Kaf
Kaf looks like a curved C-shape open to the right — a smooth curve without flat edges, like a bent bracket or a cupped hand. The curve flows continuously from the top down to the bottom with no angular corners. Kaf Sofit (ך) has the same curved top but with the leg extending far below the baseline — much longer than the regular Kaf. The name כַּף (kaf, palm) is a perfect mnemonic — the letter curves like a cupped palm.
Common Confusion: Confused with Bet (ב) — Bet has a flat base and a box shape; Kaf has a smooth curve. Also confused with Mem Sofit (ם), but only Kaf Sofit has the long descending leg. Kaf Sofit (ך) can also be confused with Nun Sofit (ן) — Kaf Sofit has a curved top, Nun Sofit has a small hook at the very top before the straight descent.
Example Words with Kaf
Here are four common Hebrew words featuring Kaf and Kaf Sofit. The first three have Kaf in initial position; the last shows Kaf Sofit at a word ending.
| Hebrew | Transliteration | English Meaning |
|---|---|---|
| כֶּלֶב | (kelev) | dog |
| כִּסֵּא | (kise) | chair |
| כֹּכָב | (kokhav) | star |
| מֶלֶךְ | (melekh) | king (ends with ך) |
How to Teach Kaf to Children
Kaf introduces the concept of sofit (final) forms — an important feature of the Hebrew alphabet. Teaching Kaf and Kaf Sofit together gives children a complete picture of this letter from the start.
Teaching Tip: Kaf Sofit (ך) is one of the five final forms (sofit letters) — it only appears at the end of words. Children should learn both forms together. A memory trick: the word כַּף (kaf) means "palm of a hand" — and the letter curves like a cupped hand. When the "palm" reaches the end of a word, its leg stretches down below the line (Kaf Sofit).
The Palm Mnemonic
The name כַּף (kaf) means "palm" — and the letter curves like an outstretched palm. Have children cup their hand and compare it to the letter shape. This physical, body-based connection makes the shape memorable and the name meaningful.
End-of-Word Pattern
Kaf Sofit (ך) always appears at the end of words. Teaching children to look at the end of a word and check for the long-legged ך is a practical reading habit. Words like מֶלֶךְ (melekh, king) and אָנֹכִי (anochi, I) end with Kaf Sofit.

Kaf Sofit (ך) is the final form of Kaf — used when Kaf appears at the end of a word. It has the same curved top as regular Kaf but the leg extends far below the baseline. The sound is the same as regular Kaf. Five Hebrew letters have sofit forms: Kaf (כ → ך), Mem (מ → ם), Nun (נ → ן), Pe (פ → ף), and Tsadi (צ → ץ).
Both can make a "kh" sound (Kaf without dagesh = Khaf; same sound as Het). But they look completely different: Het looks like a closed doorframe with two connected legs; Kaf looks like a smooth curved C-shape. In modern Hebrew they sound the same when Kaf lacks a dagesh, but they are completely different letters with different shapes.
In texts with Nikud, the dagesh dot inside Kaf tells you: with a dot (כּ) it is Kaf = "k"; without a dot it is Khaf = "kh" (like Het). In everyday Hebrew text without Nikud, you need to know the word's pronunciation from vocabulary or context — which is why children learn to read with fully pointed texts first.
Yes — Kaf is very common. It appears in everyday words like כֶּלֶב (kelev, dog), כִּסֵּא (kise, chair), and כֹּכָב (kokhav, star). The prefix כְּ- (ke-, like/as) is one of the most common Hebrew preposition prefixes. The preposition כִּי (ki, because/that) is also extremely frequent in Hebrew text.
