The Acquisition of Egyptian Arabic as a Native Language

The Acquisition of Egyptian Arabic as a Native Language

In 1968 Margaret K. Omar (Nydell) spent four months in a small Egyptian village called Sheikh Mubarak. Located in Middle Egypt near Al-Minya, residents of Sheik Mubarak speak in a dialect closer to Sa'eedi, not the dialect spoken in Cairo. Omar spent time there conducting interviews, examinations, and taping sessions with children and families to study primary language acquisition in non-Western languages. Based on her fieldwork, Omar describes the physical and social environment in which the native language was learned, the development of early communication and speech, and when and how children learn the phonology, vocabulary, morphology, and syntactical patterns of Egyptian Arabic. Omar makes comparisons with aspects of language acquisition of other languages, primarily English, and explores implications for the theory of language acquisition. Originally published in 1973, this book is the most thorough and complete analysis of the stages in which children learn Arabic as a first language. The Arabic in this book is presented in transcription, making the information accessible to all linguists interested in language acquisition.

A six-stage axial-flow compressor with a tip speed of 550 feet per second and a flat operating characteristics at constant speed has been designed and tested. It was designed for a constant power input per pound of flow in expectation that this would result in a wider mass-flow operating range at a given stagnation-presssure ratio. The design specific weight flow was 21.3 pounds per second per square foot of frontal area at atmospheric discharge with a stagnation-pressure ratio of 3.25 and an inlet hub-tip radius ratio of 0.7. Several configurations consisting of various blade setting angles and solidities were tested. Tests showed that the design flow, pressure ratio, and flat operating characteristic were obtained over a range of 10 percent of design flow at a peak efficiency of 82 percent for design conditions. The compressor had a possible immediate application for air removal from a large slotted-throat transonic wind tunnel, but the design theory could apply to any low-speed industrial compressor or second spool of a turbojet engine.

A Reference Grammar of Syrian Arabic with Audio CD

This important reissue, enhanced with an audio CD to supplement the first chapter of the text (sounds), is another addition to Georgetown's world-renowned Arabic language-learning materials and is considered to be one of the most outstanding descriptions of any Arabic dialect written for the English-speaking world. It is comprehensive in its coverage--ranging from phonology (how sounds are organized and used) to morphology (sound, syllable, and word structure), with an analysis that is insightful and original. It contains hints on how to master nuances in dialectical pronunciation, as well as the differences of meaning in their various forms. Based on the dialect of Damascus, the language covered here is part of what has variously been called "Syrian Arabic," "Eastern Arabic," and "Levantine Arabic," encompassing the dialects of Beirut, Amman, and Jerusalem--as well as Damascus--with references made to regional variants. In a world drawn ever closer to events in the Middle East, this comprehensive grammar reference is yet another extraordinary addition to the growing library of Arabic language-learning materials published by Georgetown University Press.

Modern Arabic

The revised and updated edition of Modern Arabic takes this authoritative, concise linguistic description of the structure and use of modern Arabic to an invaluable new level. Clive Holes traces the development of the Arabic language from Classical Arabic, the written language used in the 7th century for the Qur'an and poetry, through the increasingly symbiotic use of Modern Standard Arabic or MSA (the language of writing and formal speech) and dialectal Arabic (the language of normal conversation). He shows how Arabic has been shaped over the centuries by migration, urbanization, and education--giving us "a balanced, dispassionate, and accurate picture of the structures, functions, and vari...
