Throughout history, there have been two main systems of Hebrew spelling. One is vocalized spelling, the other is unvocalized spelling. In vocalized spelling (
ktiv menuqad), all of the vowels are indicated by vowel points (called
niqqud). In unvocalized spelling (
ktiv hasar niqqud, or
ktiv male), the vowel points are omitted, but can be substituted by other vowels
vav and
yud. This system is the spelling system commonly used in
Modern Hebrew today. Vowel points are always optional in Hebrew. They can be used fully, partially or not used at all. The recommended approach endorsed today by the
Academy of the Hebrew Language and other Israeli educational institutions is to use
plēnē spelling (
matres lectionis) when not adding vowel dots (which is the usual case), and place a vocalization sign on a letter only when ambiguity cannot be resolved otherwise. The
"defective" spelling is recommended for a fully vocalized text, hence its use is becoming rare. Texts older than 50–60 years may be written in an unvocalized
defective spelling (for example, the word
ḵamiším "fifty", was written on banknotes issued in
Mandatory Palestine or by the
Bank of Israel in its early days. Today, the common spelling is ). A vocalized
plene spelling system is common in
children's books, when it is better to accustom the children to the more popular
plene spelling, while still letting them benefit from the vowel dots as a reading aid in early learning stages. A third system that was endorsed in the past by the Academy of the Hebrew Language as an optimal system, but abandoned due to low popularity, calls for the use of
ḥolám (),
šurúq (),
dagéš in
Bet,
Kaf and
Pe ( vs. ),
Šin Smalít () and
mappíq (), while abandoning all other vowel dots (in everyday writing). According to this system,
matres lectionis are still introduced to mark vowels, but the letter
Vav is used only as a consonant, while its variants
ḥolám and
šurúq serve as vowel letters. This system also makes clear distinction between final
He used as a vowel marker (e.g. "a girl" ) and as a consonant (e.g. "her child"). This system was never extensively used, and the Academy of the Hebrew Language finally abandoned it in 1992, when new rules were published not assuming any use of vowel dots. Unvocalized spelling rules were instituted by the Hebrew Language Committee in 1890 (which became the
Academy of the Hebrew Language in 1953) and formally standardised in 1996. Even though the rules are established, some of the rules and specific spellings are disputed by writers and publishers, who often create their own in-house spelling system. Also, because having two spelling systems within the same language is confusing, some would like to reform it. In 2004,
Mordechai Mishor, one of the academy's linguists, proposed in a session of the Academy of the Hebrew Language a modest reform. ==Usage today==
