The roots of verbs and most nouns in the Semitic languages are characterized as a sequence of consonants or "radicals" (hence also the term consonantal root). Such abstract consonantal roots are used in the formation of actual words by adding the vowels and non-root consonants (or "transfixes") which go with a particular morphological category around the root consonants, in an appropriate way, generally following specific patterns. It is a peculiarity of Semitic linguistics that a large majority of these consonantal roots are triliterals (although there are a number of quadriliterals, and in some languages also biliterals).

A triliteral or triconsonantal root (Hebrew: שוֹרֶש‎; šoreš, Arabic: جذر ثلاثي‎; jidhr thulāthī, Syriac: ܫܪܫܐ; šeršā) is a root containing a sequence of three consonants.

The following are some of the forms which can be derived from the triconsonantal root k-t-b (general overall meaning "to write") in Hebrew and Arabic:

In Hebrew grammatical terminology, the word binyan (Hebrew בנין, plural בינינים binyanim) is used to refer to a verb stem or overall verb derivation pattern, while the word mishqal (or mishkal) is used to refer to a noun derivation pattern, and these words have gained some use in English-language linguistic terminology. The Arabic terms, called وزن wazn (plural أوزان, awzān) for the pattern and جذر jidhr (plural جذور, judhūr) for the root have not gained the same currency as the Hebrew equivalents, and Western grammarians continue to use "stem"/"form"/"pattern" for the former and "root" for the latter—though "form" and "pattern" are accurate translations of the Arabic grammatical term wazn (originally meaning 'weight, measure'), and "root" is a literal translation of jidhr.

In linguistics and ethnology, Semitic (from the Biblical "Shem", Hebrew: שם‎, translated as "name", Arabic: ساميّ‎) was first used to refer to a language family of largely Middle Eastern origin, now called the Semitic languages. This family includes the ancient and modern forms of; Akkadian, Aramaic, Hebrew, Arabic, Ge'ez, Maltese, Canaanite/Phoenician, Amorite, Eblaite, Ugaritic, Sutean, Chaldean, Mandaic, Old Persian, Ahlamu, Amharic, Tigre and Tigrinya among others.

As language studies are interwoven with cultural studies, the term also came to describe the extended cultures and ethnicities, as well as the history of these varied peoples as associated by close geographic and linguistic distribution.

The term Semite means a member of any of various ancient and modern Semitic-speaking peoples originating in southwestern Asia, including; Akkadians (Assyrians and Babylonians), Eblaites, Ugarites, Canaanites, Phoenicians (including Carthaginians), Hebrews (Israelites, Judeans and Samaritans), Ahlamu, Arameans, Chaldeans, Amorites, Moabites, Edomites, Hyksos, Arabs, Nabateans, Maganites, Shebans, Sutu, Ubarites, Dilmunites, Maltese, Mandaeans, Sabians, Syriacs, Mhallami, Amalekites and Ethiopian Semites. It was proposed at first to refer to the languages related to Hebrew by Ludwig Schlözer, in Eichhorn's "Repertorium", vol. VIII (Leipzig, 1781), p. 161. Through Eichhorn the name then came into general usage (cf. his "Einleitung in das Alte Testament" (Leipzig, 1787), I, p. 45). In his "Geschichte der neuen Sprachenkunde", pt. I (Göttingen, 1807) it had already become a fixed technical term.

Christopher Eric Hitchens (13 April 1949 – 15 December 2011) was an English American author and journalist whose career spanned more than four decades. Hitchens, often referred to colloquially as "Hitch", was a columnist and literary critic for New Statesman, The Atlantic, The Nation, The Daily Mirror, The Times Literary Supplement and Vanity Fair. He was an author of twelve books and five collections of essays. As a staple of talk shows and lecture circuits, he was a prominent public intellectual, and his confrontational style of debate made him both a lauded and controversial figure.

Hitchens was known for his admiration of George Orwell, Thomas Paine and Thomas Jefferson, as well as for his excoriating critiques of various public figures including Mother Teresa, Bill Clinton, Henry Kissinger and Diana, Princess of Wales. Although he supported the Falklands War, his key split from the established political left began in 1989 after what he called the "tepid reaction" of the Western left to the Rushdie Affair. The September 11 attacks strengthened his internationalist embrace of an interventionist foreign policy, and his vociferous criticism of what he called "fascism with an Islamic face." His numerous editorials in support of the Iraq War caused some to label him a neoconservative, although Hitchens insisted he was not "a conservative of any kind", and his friend Ian McEwan describes him as representing the anti-totalitarian left.
