Romanization of Arabic

Romanization of Arabic represents Arabic words and text with Latin letters. Systems differ in whether they preserve Arabic spelling, reflect pronunciation, or adapt words for particular languages and purposes.

Arabic alphabet: The writing system used for Arabic, written from right to left with letters that usually represent consonants. Its letters and omitted short vowels are the source forms romanization systems must represent.
DIN 31635: A German standard for romanizing Arabic, using diacritics to represent distinctions in the Arabic script. It offers a consistent scholarly mapping from Arabic letters to Latin characters.
Library cataloging: The organization of bibliographic records to make library materials identifiable and retrievable. Catalogs use standardized romanization to file Arabic titles and names consistently.
Translation: The expression of a text's meaning in another language. Romanization changes the writing system; translation changes the language and conveys meaning.
Arabic romanization variants: Different Latin-script spellings used for the same Arabic word or name. Variant spellings complicate identification when systems encode the same Arabic form differently.
Arabic phonology: The sound system of Arabic, including its consonants, vowels, and patterns of pronunciation. Pronunciation-based romanization depends on which Arabic sounds a system distinguishes.
ALA-LC Romanization: The Library of Congress system for romanizing Arabic and other languages in library catalogs. Its rules prioritize recoverable spellings for cataloging and bibliographic records.
Passport transliteration: The rendering of names from one script into another for use in passports and identity documents. Arabic personal names may receive official Latin spellings that differ from scholarly forms.
Arabic script: The right-to-left writing system used to write Arabic and several other languages. It is the original script that romanization replaces for readers using Latin letters.
Transliteration ambiguity: Uncertainty about the original text or pronunciation caused by multiple possible mappings between scripts. Some romanized Arabic forms cannot be reversed uniquely into Arabic spelling.
