Number 15 in Arabic

خمسة عشر

Pronunciation

KHAM-sa-ta A-shar (for masculine nouns) - 'kh' as in Scottish 'loch,' stress on first syllable of each part; KHAM-sa ASH-ra-ta (for feminine nouns) - same 'kh' sound, 'sh' as in 'ship,' final 'a' is short. The 'a' in 'ashar' is a short 'a' as in 'father,' and the 'r' is lightly rolled.

About This Number

The number 15 in Arabic is written as "خمسة عشر" (khamsata ashar) and consists of two parts: "خمسة" (five) and "عشر" (ten). It belongs to the compound numbers (11-19) which have unique grammatical rules in Arabic, particularly regarding gender agreement where the first part takes the opposite gender of the counted noun.

Usage Examples

خمسة عشر طالباً (khamsata ashara taaliban) - fifteen male students (masculine noun uses feminine form of number)
خمس عشرة طالبة (khamsa ashrata taalibatan) - fifteen female students (feminine noun uses masculine form of number)
خمسة عشر كتاباً (khamsata ashara kitaaban) - fifteen books (masculine noun with accusative singular)
عندي خمسة عشر درهماً (indi khamsata ashara dirhaman) - I have fifteen dirhams (used in counting money)
خمس عشرة سنة (khamsa ashrata sanatan) - fifteen years (feminine noun 'year' uses masculine number form)
في الساعة الخامسة عشرة (fi as-saa'a al-khaamisa ashrata) - at fifteen o'clock/3 PM in 24-hour format (ordinal form)

Grammar Notes

The number 15 follows the polar gender agreement rule (العدد المخالف) where the first component takes the opposite gender of the counted noun: masculine "khamsata" for masculine nouns, feminine "khamsa" for feminine nouns. The second component "ashar/ashrata" also changes gender accordingly. The counted noun always appears in the singular accusative form (منصوب), not plural, making it "fifteen book" literally rather than "fifteen books." Both parts of the compound number are written as one word and are indeclinable (مبني) in formal Arabic, though in modern usage some flexibility exists. When used as an ordinal (fifteenth), it becomes "الخامس عشر" (al-khaamas ashar) for masculine or "الخامسة عشرة" (al-khaamisa ashrata) for feminine, and both parts agree in gender with the noun.

Cultural Significance

The number 15 holds significance in the Islamic calendar as the middle of the lunar month, when the moon is full (البدر). The 15th night of Sha'ban (ليلة النصف من شعبان) is considered particularly blessed in many Muslim cultures, with special prayers and observances. In daily life, 15 is commonly encountered in contexts like half-month periods, the middle of Ramadan (a spiritually significant time), and in expressing time using the 24-hour clock system common in Arab countries.

Fun Facts

The word "خمسة" (five) shares the same root as "خميس" (Thursday), literally meaning "the fifth day" in the traditional Arab week starting from Saturday. In Arabic mathematical tradition, 15 is significant as a triangular number (the sum of 1+2+3+4+5) and appears in magic squares used by medieval Arab mathematicians. The pronunciation shift between "khamsata" and "khamsa" when changing gender demonstrates the taa marbuta (ة) characteristic of Arabic number morphology, which only appears in the masculine form for numbers 3-9 when counting.

## Understanding the Arabic Number 15: خمسة عشر (Khamsata Ashar) The number 15 in Arabic, written as **خمسة عشر** (khamsata ashar), represents a fascinating example of Arabic's complex yet logical number system. As one of the compound numbers from 11 to 19, it demonstrates unique grammatical patterns that distinguish Arabic from many other languages. ## Writing and Pronunciation of 15 in Arabic The number 15 consists of two distinct components: **خمسة** (khamsa/khamsata) meaning "five" and **عشر** (ashar/ashrata) meaning "ten." When pronouncing this number, English speakers should note that the 'kh' sound is produced from the back of the throat, similar to the 'ch' in the Scottish word "loch." The masculine form is pronounced "KHAM-sa-ta A-shar," while the feminine form is "KHAM-sa ASH-ra-ta." In written Arabic, these two parts are joined together as a single compound word, though they represent separate numerical concepts. The number reads right to left like all Arabic text, literally meaning "five and ten" in the order it appears. ## Gender Agreement Rules for 15 One of the most challenging aspects of Arabic numbers for English speakers is the gender agreement system, and 15 exemplifies the **polar gender agreement** rule (العدد المخالف). This means the number takes the opposite gender of the noun it modifies: - **Masculine nouns** require the feminine number form: خمسة عشر (khamsata ashar) - **Feminine nouns** require the masculine number form: خمس عشرة (khamsa ashrata) For example, when counting masculine "كتاب" (kitaab - book), you say "خمسة عشر كتاباً" (khamsata ashara kitaaban - fifteen books). However, with feminine "سيارة" (sayyaara - car), you say "خمس عشرة سيارة" (khamsa ashrata sayyaaratan - fifteen cars). ## The Counted Noun: Always Singular Unlike English where "fifteen" requires a plural noun ("fifteen books"), Arabic uses the **singular accusative form** of the noun after numbers 11-99. This might seem counterintuitive, but the logic is that the number itself already indicates plurality, so the noun remains singular. The accusative case is marked by the tanween sound "-an" at the end: "كتاباً" (kitaaban) rather than "كتب" (kutub - books). ## Common Usage Contexts The number 15 appears frequently in everyday Arabic: ### Time Expressions In the 24-hour clock system widely used in Arab countries, 15:00 refers to 3 PM. The ordinal form "الخامسة عشرة" (al-khaamisa ashrata) is used: "الساعة الخامسة عشرة" (as-saa'a al-khaamisa ashrata). ### Money and Commerce When discussing prices or quantities, 15 follows the same grammatical rules: "خمسة عشر درهماً" (khamsata ashara dirhaman - fifteen dirhams) or "خمس عشرة ليرة" (khamsa ashrata leeratan - fifteen liras, since lira is feminine). ### Age and Duration Expressing age uses the feminine word "سنة" (sana - year), so you would say "خمس عشرة سنة" (khamsa ashrata sanatan - fifteen years old). ## Cultural and Religious Significance The number 15 holds special importance in Islamic culture as it marks the middle of the lunar month when the moon reaches fullness. The **15th of Sha'ban** (the eighth month of the Islamic calendar) is observed by many Muslims as a blessed night called "Laylat al-Nisf min Sha'ban" (ليلة النصف من شعبان), marked by special prayers and reflection. During Ramadan, the 15th night represents the halfway point of the holy month, often bringing renewed spiritual energy to observers. Many traditional Islamic texts and hadiths reference events occurring on the 15th of various months, making this number frequently encountered in religious contexts. ## Mathematical and Linguistic Insights The structure of 15 in Arabic reflects the language's Semitic roots, where "خمسة" (five) shares its three-letter root (خ-م-س) with other related words. Interestingly, this root also gives us "خميس" (khamees - Thursday), literally meaning "the fifth day" when counting from Saturday as the first day of the traditional Arab week. In classical Arabic mathematics, 15 was recognized as a **triangular number** (the sum of the first five natural numbers: 1+2+3+4+5=15), a property that fascinated medieval Arab mathematicians who contributed significantly to number theory and algebra. ## Tips for English Speakers When learning to use 15 in Arabic, remember these key points: 1. Always check the gender of your noun first 2. Apply the opposite gender to the number 3. Keep the noun singular and in the accusative case 4. Practice both forms regularly since gender mistakes are common 5. Listen to native speakers to master the pronunciation nuances Mastering the number 15 and its compound number siblings (11-19) is a significant milestone in learning Arabic, as these numbers demonstrate core grammatical principles that extend throughout the language's number system.
