The dagesh () is a diacritic that is used in the Hebrew alphabet. It takes the form of a dot placed inside a consonant.
A dagesh can either indicate a "hard" plosive version of the consonant (known as , literally 'light dot') or that the consonant is geminated (known as , literally 'hard dot').
In Modern Hebrew, the dagesh only changes the pronunciation of ÃÂâ bet, ÃÂâ kaf, and äâ pe: in those letters, it turns a fricative sound (vet, khaf, and fe) into a plosive sound (bet, kaf, and pe), regardless of the dagesh's grammatical/orthographic origin, kal or ḥazaq; gemination itself (lengthening of the consonant) is generally not pronounced in any consonant.
The dagesh was added to Hebrew orthography at the same time as the Masoretic system of niqqud (vowel points).
Two other diacritics with different functions, the mappiq and the shuruq dot, are visually identical to the dagesh but are only used with vowel letters.
The dagesh and mappiq symbols are usually omitted when writing without niqqud (e.g. is written as ), however, dagesh may be added to words that would be ambiguous without niqqud. The use or omission of such marks is usually consistent throughout any given context.
A or (, or , also lene, weak/light dagesh) may be placed inside the consonants , , , , and . They each have two sounds, the original hard plosive sound (which originally contained no as it was the only pronunciation), and a soft fricative version produced as such for speech efficiency because of the position in which the mouth is left immediately after a vowel has been produced.
Although there is debate, some scholars suggest that prior to the Babylonian captivity, the soft sounds of these letters did not exist in Hebrew, but they were later differentiated in Hebrew writing as a result of the Aramaic-influenced pronunciation of Hebrew. The Aramaic languages, including Jewish versions of Aramaic, have these same allophonic pronunciations of the letters.
The letters take on their hard sounds when they have no vowel sound before them, and take their soft sounds when a vowel immediately precedes them. In Biblical Hebrew this was the case within a word and also across word boundaries, though in Modern Hebrew there are no longer across word boundaries, since the soft and hard sounds are no longer allophones of each other, but regarded as distinct phonemes.
When vowel diacritics are used, the hard sounds are indicated by a central dot called , while the soft sounds lack the mark. In Modern Hebrew, however, the only changes the pronunciation of , , and . Traditional Ashkenazic pronunciation also varies the pronunciation of , as does Yemenite pronunciation. Some traditional Middle Eastern pronunciations carry alternate forms for .
In Ashkenazi pronunciation, without a is pronounced , while in other traditions it is assumed to have been pronounced at the time was introduced. In Modern Hebrew, it is always pronounced .
The letters () and () may also contain a . This indicates an allophonic variation of the phonemes and , a variation which no longer exists in modern Hebrew pronunciation. The variations are believed to have been: pronounced as , as , as , and as . The Hebrew spoken by the Jews of Yemen (Yemenite Hebrew) still preserves unique phonemes for these letters with and without a dagesh.
Among Modern Hebrew speakers, the pronunciation of some of the above letters has become the same as others:
or (, , i.e. 'gemination ', or , also ' forte') may be placed in almost any letter, indicating a gemination (doubling) of that consonant in the pronunciation of pre-modern Hebrew.
This gemination is not adhered to in modern Hebrew and is only used in careful pronunciation, such as the reading of scripture in a synagogue service, recitation of biblical or traditional texts or on ceremonial occasions, and only by very precise readers. However, the rules of the dagesh ḥazak still influence pronunciation in modern Hebrew, though not by gemination: in all cases where Biblical Hebrew geminates a letter, modern Hebrew retains a dagesh inside the letter, which influences pronunciation in the following way: in ÃÂâ bet, ÃÂâ kaf, and äâ pe, it turns a fricative sound (vet, khaf, and fe) into a plosive sound (bet, kaf, and pe); in all other letters, it is not pronounced.
The following letters, the gutturals, almost never have a : , , , , and . A few instances of with are recorded in the Masoretic Text, as well as a few cases of with , such as in Leviticus 23:17.
The presence of a or consonant-doubling in a word may be entirely morphological, or, as is often the case, is a lengthening to compensate for a deleted consonant. A may be placed in letters for one of the following reasons:
In Masoretic manuscripts the opposite of a would be indicated by a , a small horizontal line on top of the letter. This is no longer found in Hebrew, but may still sometimes be seen in Yiddish and Ladino.
In computer typography there are two ways to use a with Hebrew text. The following examples give the Unicode and numeric character references:
Some fonts, character sets, encodings, and operating systems may support neither, one, or both methods.
