Context paragraphs:
Iranian languages: The Iranian languages or Iranic languages are a branch of the Indo-Iranian languages, which in turn are a branch of the Indo-European language family.  The speakers of Iranian languages are known as Iranian peoples.  Historical Iranian languages are grouped in three stages: Old Iranian (until 400 BC), Middle Iranian (400 BC – 900 AD), and New Iranian (since 900 AD).  Of the Old Iranian languages, the better understood and recorded ones are Old Persian (a language of Achaemenid Iran) and Avestan (the language of the Avesta).  Middle Iranian languages included Middle Persian (a language of Sassanid Iran), Parthian, and Bactrian.

Algonquian languages: also Algonkian) are a subfamily of Native American languages which includes most of the languages in the Algic language family.  The name of the Algonquian language family is distinguished from the orthographically similar Algonquin dialect of the indigenous Ojibwe language (Chippewa), which is a senior member of the Algonquian language family.  The term "Algonquin" has been suggested to derive from the Maliseet word "elakómkwik" (pronounced ] ), "they are our relatives/allies".  A number of Algonquian languages, like many of the Iroquoian languages of the hereditary enemies of the Algonquian peoples, have already become extinct.

Danish Sign Language family: The Danish Sign Language family comprises three languages: Danish Sign Language, Norwegian Sign Language (including Malagasy Sign Language) and Icelandic Sign Language.  It itself is a sub-language family within the larger French Sign Language family.

Old Chiangmai–Bangkok Sign Language family: The Old Chiangmai–Bangkok Sign Language family is a language family of two related sign languages: Old Chiangmai Sign Language and Old Bangkok Sign Language.  Woodward (2003) found that they were 65% cognate, indicating that the two languages are related, possibly due to migration between Chiangmai and Bangkok.  There appear to be connections to sign languages of Vietnam (especially to Hai Phong Sign Language), and possibly Laotian sign languages, but the nature of these connections (whether areal or genetic) has not been determined.  Village sign languages of Thailand, such as Ban Khor Sign Language, are unrelated.

German Sign Language family: The German Sign Language family is a small language family of sign languages, including German Sign Language, Polish Sign Language and probably Israeli Sign Language.  The latter also had influence from Austrian Sign Language, which is unrelated, and the parentage is not entirely clear.

Že: Že, or žayn/žāy (ژ ), is a letter in the Perso-Arabic alphabet, based on "zayn" (ز ) with two additional diacritic dots.  It is found with this value in other Arabic-derived scripts.  It is used in Persian, Pashto, Kurdish, other Iranian languages, Uyghur, Ottoman Turkish, Azerbaijani and Urdu, but not in Arabic.  However, it might be used in Arabic texts to represent other phonemes when writing words with sounds not in Arabic letters.  It is used to represent the sound /<a href="">ʒ/ or sometimes /<a href="">zˤ/ , just like the letter "ẓāʼ" (ظ ).  In modern Turkish alphabet J equals to ژ.

Language family: A language family is a group of languages related through descent from a common "ancestral language" or "parental language", called the proto-language of that family.  The term "family" reflects the tree model of language origination in historical linguistics, which makes use of a metaphor comparing languages to people in a biological family tree, or in a subsequent modification, to species in a phylogenetic tree of evolutionary taxonomy.  Linguists therefore describe the "daughter languages" within a language family as being "genetically related".

Austronesian languages: The Austronesian languages are a language family that is widely dispersed throughout Maritime Southeast Asia, Madagascar and the islands of the Pacific Ocean, with a few members in continental Asia.  Austronesian languages are spoken by about 386 million people, making it the fifth-largest language family by number of speakers, behind only the Indo-European languages, the Sino-Tibetan languages, the Niger-Congo languages, and the Afroasiatic languages.  It is on par with Indo-European, Niger–Congo, and Afroasiatic as one of the best-established language families.  Major Austronesian languages with the highest number of speakers are Malay (Indonesian and Malaysian), Javanese, and Filipino (Tagalog).  The family contains 1,257 languages, which is the second most of any language family.

Elamo-Dravidian languages: The Elamo-Dravidian language family is a hypothesised language family that links the Dravidian languages of India to the extinct Elamite language of ancient Elam (present-day southwestern Iran).  Linguist David McAlpin has been a chief proponent of the Elamo-Dravidian hypothesis.  According to McAlpin, the long-extinct Harappan language (the language or languages of the Indus Valley Civilization) might also have been part of this family.  The hypothesis has gained attention in academic circles, but has been also been subject to serious criticism by other linguists, and remains only one of several scenarios for the origins of the Dravidian languages.

Tungusic languages: The Tungusic languages (also known as Manchu-Tungus, Tungus) form a language family spoken in Eastern Siberia and northeast China by Tungusic peoples.  Many Tungusic languages are endangered, and the long-term future of the family is uncertain.  There are approximately 75,000 native speakers of the dozen living languages of the Tungusic language family.  Some linguists consider Tungusic to be part of the generally-rejected Altaic language family, along with Mongolic, and sometimes Koreanic and Japonic.
