Number 40 in Arabic

أربعون

Pronunciation

Ar-BAH-oon (nominative form). The stress falls on the final syllable. The 'Q' sound (ق) is a deep, guttural sound produced in the back of the throat — similar to a 'k' but deeper and more emphatic. Pronounce each syllable clearly: ar (like the letter 'R' in English) + bah (rhymes with 'spa') + oon (like 'noon' in English). For the accusative form أربعين (ar-BAH-een), the final syllable changes to rhyme with 'seen' rather than 'noon.'

About This Number

أربعون (arba'un) is the Arabic number 40, representing a round tens number in the Arabic numeral system. It is masculine in gender and is used both as a standalone number and in compound numbers (41-49). This number follows unique grammar rules common to tens in Arabic, requiring special attention to gender agreement and noun pairing.

Usage Examples

أربعون طالباً (arba'un taaliban) — 'forty students' (masculine). The noun takes the accusative case after the number.
أربعون سنة (arba'un sanah) — 'forty years.' When paired with feminine nouns, the number remains in its base form but the noun takes accusative case.
لديّ أربعون كتاباً في مكتبتي (ladayya arba'un kitaban fi maktabati) — 'I have forty books in my library.'
قضى موسى أربعين سنة في البرية (qada Musa arba'ina sanah fi al-bariyyah) — 'Moses spent forty years in the wilderness.' Note: أربعين (arba'in) is the accusative/genitive form.
هناك أربعون شخصاً في الاجتماع (hunaka arba'un shakhsan fi al-ijtima') — 'There are forty people in the meeting.'
اشتريت أربعين تفاحة من السوق (ishtaraytu arba'in tuffaha min as-suq) — 'I bought forty apples from the market.' Here أربعين shows the accusative form used after verbs.

Grammar Notes

أربعون (arba'un) is a tens number that requires careful gender and case agreement. In the nominative case, it appears as أربعون and is considered masculine. When used with both masculine and feminine nouns, the number typically maintains its masculine form, but the following noun must be in the accusative case (منصوب) and appear in the plural form. In the accusative and genitive cases, أربعون becomes أربعين (arba'in). Importantly, tens numbers (20, 30, 40, etc.) are treated as dual-like constructs in classical Arabic, meaning they govern nouns differently than other numbers; the noun after a tens number should be accusative plural. Additionally, when أربعون appears in compound numbers (41-49), the construction follows the pattern of 'ones + tens,' where both numbers must agree in case with the following noun.

Cultural Significance

The number 40 holds profound significance in Islamic and Arab tradition, appearing frequently in the Quran and Islamic history. Most notably, the Prophet Muhammad spent 40 years before receiving revelation, and Muslims fast for 30 days during Ramadan with an additional 10 days of Shawwal often observed, totaling 40. The number also appears in numerous Quranic stories, such as Prophet Musa (Moses) spending 40 years in the wilderness and the Children of Israel's 40-year journey. In Arab culture, 40 is associated with wisdom, maturity, and completion, making it a spiritually and culturally loaded number.

Fun Facts

The word أربعون (arba'un) derives from the root ر-ب-ع, which relates to the concept of 'four' — as 40 is four tens. In everyday Arabic, the number 40 appears frequently in colloquial expressions and proverbs; for example, 'after forty' (بعد الأربعين) often marks a significant life transition. Interestingly, the form أربعين (arba'in) in the accusative/genitive case is used more frequently in narrative and religious texts than the nominative form, as these texts often describe events involving 'forty' in specific contexts requiring oblique cases.

## Arabic Number 40: أربعون (Arba'un) ### Introduction to 40 in Arabic The number 40 in Arabic is written as **أربعون** (arba'un) in its nominative form and **أربعين** (arba'in) in its accusative and genitive forms. Understanding this number is essential for Arabic learners because tens numbers follow distinct grammar patterns that differ from cardinal numbers 1-19 and higher compound numbers. The number 40 represents a significant threshold in Arabic counting and appears frequently in everyday speech, religious texts, and classical literature. ### Pronunciation Guide To pronounce أربعون correctly, break it into three syllables: **ar-BAH-oon**. The stress falls on the second-to-last syllable. The Arabic letter ق (qaf) produces a deep, guttural sound from the back of the throat that has no direct English equivalent—think of it as an emphatic 'k' sound. The final ون (-oon) rhymes with the English word 'noon.' When the number shifts to accusative/genitive form (أربعين), the pronunciation becomes **ar-BAH-een**, with the final syllable rhyming with 'seen.' ### Grammar Rules for Tens Numbers In Arabic, tens numbers (20, 30, 40, 50, etc.) operate under a unique grammatical system distinct from other cardinal numbers. Here are the critical rules: **1. Case System:** أربعون is nominative (المرفوع), while أربعين is both accusative (المنصوب) and genitive (المجرور). The case depends on the grammatical function within the sentence. For example: - Nominative: هناك أربعون طالباً (There are forty students) - Accusative: رأيت أربعين كتاباً (I saw forty books) - Genitive: في البيت أربعين كتاب (In the house [are] forty books) **2. Gender Agreement:** Unlike numbers 3-19, which show strict gender agreement (feminine forms for masculine nouns and vice versa), the number 40 remains masculine regardless of whether it modifies masculine or feminine nouns. This characteristic is consistent across all tens numbers. **3. Noun Case Requirements:** The noun following أربعون or أربعين must ALWAYS be in the accusative case (منصوب) and must be plural. This is a defining feature of tens numbers and distinguishes them from other counting systems: - Correct: أربعون طالباً (forty students - accusative plural) - Incorrect: أربعون طالب (this form is not standard in modern Arabic) **4. Agreement in Compound Numbers:** When 40 appears in compound numbers (41-49), the structure follows the pattern "ones number + tens number." Both components must agree in case with the modified noun. For example: اثنان وأربعون (42) would require both components to shift case together. ### Usage Examples in Context **Example 1: Simple Statement** أربعون طالباً يدرسون الرياضيات (Forty students are studying mathematics) - Here, أربعون is nominative because it serves as the subject of the sentence - طالباً is accusative plural, as required after tens numbers **Example 2: After a Verb (Past Tense)** اشتريت أربعين قلماً من المكتبة (I bought forty pens from the library) - أربعين is accusative because it follows the past tense verb اشتريت - قلماً is also accusative plural **Example 3: Religious/Historical Context** صام الرسول أربعين يوماً (The Prophet fasted for forty days) - Here أربعين is accusative, indicating the duration of fasting - يوماً is accusative plural **Example 4: Prepositional Phrase** في الفصل أربعون طالبة (In the classroom are forty female students) - When tens numbers appear after prepositions, they remain in the same case system - The noun remains accusative plural **Example 5: Possession** لدي أربعون كتاباً في مكتبتي (I have forty books in my library) - After the preposition ل (to/for), the case agreement follows the overall sentence structure - The accusative form أربعون is used here ### Nominative vs. Accusative/Genitive Forms Understanding when to use أربعون versus أربعين is crucial: - **Use أربعون (nominative)** when the number functions as the subject or predicate nominative: "هناك أربعون شخص" (There are forty people) - **Use أربعين (accusative/genitive)** when the number is the object of a verb or preposition: "رأيت أربعين كتاباً" (I saw forty books) or "من بين أربعين خيار" (from among forty options) ### Historical and Cultural Significance The number 40 appears throughout Islamic history and religious texts with remarkable frequency. In the Quran, 40 is mentioned in numerous contexts: Prophet Musa spent 40 years in the wilderness, Prophet Muhammad received revelation at age 40, and the Children of Israel were tested for 40 years in the desert. This recurring appearance has made 40 a number of spiritual weight in Islamic culture. Beyond religious significance, the number 40 marks important life transitions in Arab society. The phrase "بعد الأربعين" (after forty) colloquially references the point at which a person reaches mature adulthood, and many Arab traditions recognize the 40th day after significant events (birth, death) as spiritually significant. ### Common Phrases and Expressions - أربعون سنة (forty years) — commonly used in historical narratives - كل أربعين يوماً (every forty days) — used in medical or religious contexts - أربعون ليلة (forty nights) — appears in classical and religious texts - أربعون مرة (forty times) — used when discussing repetition or emphasis ### Comparison with Other Tens Numbers The grammar rules for 40 are identical to those for 20, 30, 50, 60, 70, 80, and 90. All tens numbers share these characteristics: masculine gender, accusative plural nouns, and dual case forms. However, the number 40 is unique in its cultural and religious prominence, making it perhaps the most frequently encountered tens number in both classical and modern Arabic texts. ### Practical Tips for Learning 1. **Memorize the Case Forms:** Create flashcards with أربعون (nominative) and أربعين (accusative/genitive) to reinforce the distinction. 2. **Practice with Nouns:** Regularly construct sentences using أربعون with different nouns to internalize the accusative plural requirement. 3. **Read Religious Texts:** The Quran and Hadith texts provide authentic, classical examples of how 40 is used in traditional Arabic. 4. **Listen to Native Speakers:** Audio resources can help you hear the correct pronunciation and stress patterns. ### Conclusion Mastering the number 40 and its grammar rules is an important step in Arabic proficiency. The distinction between أربعون and أربعين, combined with the requirement for accusative plural nouns, represents a core feature of Arabic's case and number system. By understanding these patterns, learners can apply them to all tens numbers and significantly improve their grammatical accuracy in Arabic communication.
