خمسون
KAHM-soon. Break it into two syllables: KAHM (rhymes with 'mom') and soon (rhymes with 'moon'). The emphasis falls on the first syllable. When used in the accusative or genitive case, it becomes KAHM-seen (with the 'sun' sound changing to 'seen'). Practice saying it slowly: kh-AHM-soon, where the 'kh' is guttural, similar to the 'ch' in the German word 'Bach.'
خمسون (khamsun) is the Arabic word for the number 50, a tens number in the Arabic counting system. It is masculine in form and is used in cardinal counting, telling time, and describing quantities. Like other tens numbers in Arabic, khamsun has specific grammatical rules for agreement with nouns and can be modified with different case endings depending on its position in a sentence.
خمسون (khamsun) is a masculine noun grammatically, though it can be used with both masculine and feminine nouns without gender agreement changes to the number itself. However, the noun it precedes must be in the accusative case (منصوب - mansub) and in the plural form when directly preceded by the number. When 50 appears in a sentence as the subject (nominative case), it retains the form خمسون; in the accusative case, it becomes خمسين (khamsin); and in the genitive case, it also becomes خمسين (khamsin). The dual forms (50-99) are considered nouns themselves and behave differently from units (1-9) and tens (20, 30, 40, etc.). When counted with a noun, the noun must be plural and in the accusative case, such as خمسون طالباً (khamsun taliban — fifty students, with taliban in accusative plural). The numbers 50, 60, 70, 80, and 90 all follow this same pattern of three-case declension.
The number 50 holds moderate cultural significance in Islamic tradition, as it appears in various contexts including the Quran and Islamic jurisprudence. Most notably, fifty is associated with important Islamic practices: according to Islamic tradition, the initial obligation of daily prayers was fifty, before being reduced to five through Prophet Muhammad's negotiation during the Night Journey (Isra and Mi'raj). In everyday Arabic culture, 50 is frequently encountered in commercial transactions, age references, and administrative contexts across the Arab world, making it one of the most practically useful numbers in daily communication.
The word خمسون comes from the root خمس (khams), which means 'five,' reflecting the Arabic numerical system's logical construction where larger numbers are built from smaller foundational numbers. In classical Arabic mathematics and astronomy, the number 50 held particular importance in calculations and divisions, especially in Islamic geometric patterns and architectural designs. The number 50 also appears in traditional Arabic poetry and literature as a symbolic number representing maturity and wisdom, often used metaphorically in classical texts.
