Figure out which of the mentioned "Arabic languages" you would like to learn.
Get to know the main differences of the Arabic language from English.
Buy exercise books containing samples of the most popular Arabic writings: "ruq'a," which is used in books, and the more informal "naskh."
Learn the Arabic alphabet by heart. It consists of the letters for consonants called "khuruf" (single -- "kharf"). Arabs use facultative signs for vowels, which are written above and under the line in the Qur'an, dictionaries and educational texts. Pay attention to guttural and emphatic consonants. Study "solar" and "lunar" khuruf. For example, the "solar" khuruf start a word assimilate element "l" of a definite article. This means "Sharm-al-Sheikh" is pronounced as "Sharm-ash-Sheikh," while the "lunar" khuruf do not assimilate the article, like in "Al-Jazeera."
Write from right to left.
Learn the Arabic system of personal pronouns, understanding how it's different from the English system. Unlike English, Arabic has three pronouns corresponding to 'they:" one in dual number for both genders, and separate pronouns in plural for feminine and masculine. Also, it has five pronouns corresponding to "you:" masculine and feminine singular forms, dual form for both genders and plural forms for each gender.
Learn the category of numbers, including single, dual and plural numbers.
Make sure you understand the idea of a tri-consonantal root: Each word in Arabic has a root consisting of a sequence of three "khuruf" (consonants), although there are rare roots made up of four or five consonants.
Learn several frequently used words, like a male student (talib), a female student (taliba), a house (bait) and a school (madrasa). Familiarize yourself with the gender categories and the category of regular and irregular ("broken") plural numbers of the nouns.
Memorize numerals up to 100 in both genders.
Learn frequently used prepositions such as "in," "to," "with" and "from."
Create simple phrases using the vocabulary you have learned, like "he is at school" and "they are at home."
Put adjectives after nouns in sentences.
Familiarize yourself with the concept of definite and indefinite articles (the latter is attached to the end of any word except for verbs and prepositions and also indicates three cases of the Arabic language: nominative, genitive and accusative).
Learn the concept of the genitive construction, or "idafa" (addition), which corresponds to a sequence of two or more nouns, numerals or adjectives followed by a noun. This is similar to such English constructions as "a bridge of stone," "a ring of gold," "blue-eyed" and "the chamber of commons," where the following word defines the preceding one and very often indicates the material. This genitive construction juxtaposes to the attributive construction of a noun followed by adjective.
Realize the concept of modeling. The majority of words in the Arabic language are constructed according to models that look very similar to algebraic formulas. They consist of a sequence of permanent elements including consonant and vowel elements with the empty cells for consonants representing tri-consonantal roots of any word.
Learn 15 compulsory models of the Arabic verb. These models (formulas) reflect such meanings as activeness, passiveness, causative character of a verb and reflexiveness.
Memorize the most frequent models corresponding to nouns, adjectives and numerals.
