Ancient Hebrew language

Ancient Hebrew (ISO 639-3 code hbo) is a blanket term for varieties of the Hebrew language used in ancient times. It can be divided into:

See also: Ancient Hebrew writings.

Noun

A noun (from Latin nōmen, literally meaning "name") is a word that functions as the name of some specific thing or set of things, such as living creatures, objects, places, actions, qualities, states of existence, or ideas.Linguistically, a noun is a member of a large, open part of speech whose members can occur as the main word in the subject of a clause, the object of a verb, or the object of a preposition.

Lexical categories (parts of speech) are defined in terms of the ways in which their members combine with other kinds of expressions. The syntactic rules for nouns differ from language to language. In English, nouns are those words which can occur with articles and attributive adjectives and can function as the head of a noun phrase.

History

Word classes (parts of speech) were described by Sanskrit grammarians from at least the 5th century BC. In Yāska's Nirukta, the noun (nāma) is one of the four main categories of words defined.

The Ancient Greek equivalent was ónoma (ὄνομα), referred to by Plato in the Cratylus dialog, and later listed as one of the eight parts of speech in The Art of Grammar, attributed to Dionysius Thrax (2nd century BC). The term used in Latin grammar was nōmen. All of these terms for "noun" were also words meaning "name". The English word noun is derived from the Latin term, through the Anglo-Norman noun.

Hebrew alphabet

The Hebrew alphabet (Hebrew: אָלֶף־בֵּית עִבְרִי, alefbet ʿIvri), known variously by scholars as the Jewish script, square script, block script, is used in the writing of the Hebrew language, as well as of other Jewish languages, most notably Yiddish, Ladino, and Judeo-Arabic. There have been two script forms in use; the original old Hebrew script is known as the paleo-Hebrew script (which has been largely preserved, in an altered form, in the Samaritan script), while the present "square" form of the Hebrew alphabet is a stylized form of the Aramaic script and was known by Israel's sages as the Ashuri script (Assyrian script), since its origins were alleged to be from Assyria. Various "styles" (in current terms, "fonts") of representation of the letters exist. There is also a cursive Hebrew script, which has also varied over time and place.

The Hebrew alphabet has 22 letters. It does not have case, but five letters have different forms when used at the end of a word. Hebrew is written from right to left. Originally, the alphabet was an abjad consisting only of consonants. As with other abjads, such as the Arabic alphabet, scribes later devised means of indicating vowel sounds by separate vowel points, known in Hebrew as niqqud. In rabbinic Hebrew, the letters א ה ו י are also used as matres lectionis (the use of certain consonants to indicate a vowel) to represent vowels. When used to write Yiddish, the writing system is a true alphabet (except for borrowed Hebrew words). In modern usage of the alphabet, as in the case of Yiddish (except that ע replaces ה) and to some extent modern Israeli Hebrew, vowels may be indicated. Today, the trend is toward full spelling with these letters acting as true vowels.

Research institute

A research institute is an establishment endowed for doing research. Research institutes may specialize in basic research or may be oriented to applied research. Although the term often implies natural science research, there are also many research institutes in the social sciences as well, especially for sociological and historical research purposes.

Famous research institutes

In the early medieval period, several astronomical observatories were built in the Islamic world. The first of these was the 9th-century Baghdad observatory built during the time of the Abbasid caliph al-Ma'mun, though the most famous were the 13th-century Maragheh observatory, 15th-century Ulugh Beg Observatory.

The earliest research institute in Europe was Tycho Brahe's Uraniborg complex on the island of Hven, a 16th-century astronomical laboratory set up to make highly accurate measurements of the stars. In the United States there are numerous notable research institutes including Bell Labs, The Scripps Research Institute,Beckman Institute, and SRI International. Hughes Aircraft used a research institute structure for its organizational model.
