خمسة وثمانون
KAHM-sah wah THAH-mah-noon. Break it down: KAHM-sah (five, with a flat 'a' sound), wah (and, similar to 'wa' in English 'wand'), THAH (with a soft 'th' like in 'this'), mah-noon (the 'oo' as in 'moon'). Emphasize the first syllable of khamsa and the middle syllable of thamanun.
The number 85 in Arabic is written as خمسة وثمانون and is composed of the units number خمسة (five) combined with the tens number ثمانون (eighty). It follows the Arabic pattern of stating the smaller number first, followed by 'wa' (and), then the larger number, which is the reverse of English ordering.
The number 85 demonstrates complex gender and case agreement rules in Arabic. The units number خمسة (five) takes the opposite gender of the counted noun—if the noun is masculine, خمسة is feminine, and vice versa. The tens number ثمانون (eighty) can take either gender but typically agrees with the noun's gender as well. When used in construction with nouns, خمسة وثمانون remains in the nominative case (with tanween on خمسة: خمسة) when functioning as a standalone number, but the counted noun that follows must be in the accusative case (منصوب) and typically in the plural form for numbers 3-10, though numbers 11+ usually take the singular. The entire compound number maintains its structure even when declined for case—the 'wa' conjunction remains unchanged, and both the units and tens components preserve their inherent case structure based on their position in the sentence.
While 85 does not hold specific religious or mystical significance in Islamic tradition, it appears frequently in Arab demographics and historical contexts. The number is commonly encountered in discussions of elder respect in Arab culture, as 85 represents advanced age worthy of honor and reverence within Islamic and Arab traditions that emphasize care for the elderly.
The number 85 is interesting linguistically because it demonstrates the Arabic principle of 'reverse ordering' where units precede tens—a feature that distinguishes Arabic numerals from Western convention. In Arabic mathematical tradition, 85 is considered a composite number with pedagogical value in teaching multiplication and factorization. The Arabic word ثمانون (eighty) derives from the root ث م ن, which relates to price and value, reflecting the historical connection between counting and commerce in Arabic-speaking societies.
