Kamatz or qamatz (Modern Hebrew: קָמָץ, IPA:; alternatively קָמֶץ qāmeṣ) is a Hebrew niqqud (vowel) sign represented by two perpendicular lines (looking like an uppercase T) ⟨ ָ ‎ ⟩ underneath a letter. In modern Hebrew, it usually indicates the phoneme /a/ which is the "a" sound in the word spa and is transliterated as a. In these cases, its sound is identical to the sound of pataḥ in modern Hebrew. In a minority of cases it indicates the phoneme /o/, equal to the sound of ḥolam. In traditional Ashkenazi Hebrew pronunciation, qamatz is pronounced as the phoneme /ɔ/, which becomes /u/ in some contexts in southern Ashkenazi dialects.

### Qamatz Qaṭan vs. Qamatz Gadol

| Biblical Hebrew | Tiberian phoneme | Tiberian vowel | Babylonian phoneme | Modern Hebrew |
| /a/ | [a] | Patach | [a] | Patach |
| /aː/ | [ɔ] | Kamatz | [a] | Kamatz Gadol |
| /o/ | [ɔ] | Kamatz | [o] | Kamatz Katan |
| /oː/ | [o] | Holam | [o] | Holam |
The Hebrew of the late centuries BCE and early centuries of the Common Era had a system with five phonemic long vowels /aː eː iː oː uː/ and five short vowels /a e i o u/.
In the later dialects of the 1st millennium CE, phonemic vowel length disappeared, and instead was automatically determined by the context, with vowels pronounced long in open syllables and short in closed ones. However, the previous vowel phonemes merged in various ways that differed from dialect to dialect:
* In Tiberian Hebrew, which underlies the written system of vowels, short /a/ became [a] (indicated by pataḥ); long /oː/ became [o] (indicated by ḥolam); while /aː/ and /o/ both merged into an in-between sound [ɔ] (similar to the vowel in English "caught" without the cot-caught merger), which was indicated by qamatz.
* In the Babylonian vocalization, however, short and long variants simply merged, with /a/ and /aː/ becoming [a], while /o/ and /oː/ became [o]; and this system underlies the pronunciation of Modern Hebrew.
The result is that in Modern Hebrew, the vowel written with qamatz might be pronounced as either [a] or [o], depending on historical origin. It is often said that the two sounds can be distinguished by context:
* The qamatz sound of [o], known as Qamatz Qaṭan (Hebrew: קָמַץ קָטָן, IPA:, "little qamatz") occurs in a "closed syllable", i.e. one which ends in a consonant marked with a shwa nakh (zero vowel) or with a dagesh ḥazaq (which indicates that the consonant was pronounced geminated, i.e. doubled);
* The qamatz sound of [a], known as Qamatz Gadol (Hebrew: קָמַץ גָּדוֹל, "big qamatz") occurs in an "open syllable", i.e. any other circumstance: one which ends in a consonant followed by a normal vowel, a consonant at the end of a word and with no vowel marking, or a consonant marked with a shwa na (originally pronounced [ə]).
Unfortunately, the two varieties of shwa are written identically, and pronounced identically in Modern Hebrew; as a result, there is no reliable way to distinguish the two varieties of qamatz when followed by a vowel marked with a shwa. (In some cases, Biblical texts are marked with a metheg or other cantillation mark that helps to indicate which pronunciation is intended, but this usage is not consistent, and in any case such marks are absent in non-Biblical texts.) It should also be noted that there are examples of qamatz qaṭan appearing in open syllables, such as in the plural of שֹׁרֶשׁ‎ (, "root"), שׇׁרָשִׁים‎.
An example of the qamatz qatan is the Modern Hebrew word תׇּכְנִית‎ (, "program").
According to the standard Hebrew spelling rules as published by the Academy of the Hebrew Language, words which have a qamatz qatan in their base form must be written without a vav, hence the standard vowel-less spelling of תׇּכְנִית‎ is תכנית‎. In practice, however, Modern Hebrew words containing a qamatz qatan do add a vav ⟨ו‎⟩ to indicate the [o] pronunciation; hence the nonstandard (also termed "excessive") spelling תוכנית‎ is common in newspapers and is even used in several dictionaries, for example Rav Milim. Words which in their base form have a ḥolam that changes to qamatz qaṭan in declension retain the vav in vowel-less spelling: the noun חֹפֶשׁ‎ (, "freedom") is spelled חופש‎ in vowel-less texts; the adjective חָפְשִׁי‎ (, "free") is spelled חופשי‎ in vowel-less text, despite the use of qamatz qatan, both according to the standard spelling and in common practice.
Some books print the qamatz qaṭan differently, although the way in which they do is not consistent. For example, in siddur Rinat Yisrael the vertical line of qamatz qatan is longer. In Siddur Sim Shalom, the horizontal line is separated from the bottom. In a book of Psalms used by some Breslov hassidim the qamatz qatan is bolder. In the popular niqqud textbook Niqqud halakha le-maase by Nisan Netser, the qamatz qatan is printed as an encircled qamatz for didactic purposes.
Unicode defines the code point U+05C7 ׇ HEBREW POINT QAMATS QATAN, although its usage is not required.

### Ḥaṭaf Qamatz

Ḥaṭaf Qamatz (Hebrew: חֲטַף קָמַץ, IPA:) is a "reduced qamatz". Like qamatz qatan, it is pronounced [o], but the rationale for its usage is different: it replaces the shva on letters which require a shva according to the grammar, but where the traditional pronunciation is [o]. This mostly happens with gutturals, for example in אֳרָנִים‎ (, "pines", the plural form of אֹרֶן‎,), but occasionally also on other letters, for example שֳׁרָשִׁים‎ (, "roots", another plural of שֹׁרֶשׁ‎); and צִפֳּרִים‎ (, "birds", the plural of צִפּוֹר‎.

## Vowel length comparison

These vowel lengths are not manifested in Modern Hebrew. The short o (qamatz qaṭan) and long a (qamatz) have the same niqqud. Because of this, the short o (Qamatz Qaṭan) is usually promoted to a long o (holam male) in Israeli writing, written as a vav ⟨ו‎⟩, for the sake of disambiguation.
By adding two vertical dots (shva) the vowel is made very short.
