is noted as a frequent source of error for speakers and writers in media and formal communication. Mastering it requires understanding the interplay between the quantity and the specific noun being quantified. تعلم العربية
The "ones" part is opposite in gender, while "ten" ('ashara) matches the ma’dud.
Tarkib Adadi is far more than a grammatical oddity. It is a testament to the precision and structural elegance of classical Arabic grammar. By imposing a set of rigid rules—indeclinability, inverted gender, singular accusative nouns—on the numbers 11 through 19, the language achieves a remarkable clarity. Understanding this numerical composition is essential not only for counting correctly but for appreciating how Arabic, like a master architect, designs even its most functional phrases with logical beauty. Whether one is reading a medieval mathematical manuscript or simply buying nineteen apples in a Cairo market, the principles of tarkib adadi quietly ensure that quantity and clarity go hand in hand.
Instead of changing their physical vowels, they occupy a structural position ( Fi Mahalli ):
The gender of the number must be the exact opposite of the singular form of the counted noun. If the singular noun is masculine, use a feminine number (with a Ta-Marbuta ). tarkib adadi
These are "compound" numbers ( Tarkib Majzi ). They are typically indeclinable ( Mabni ) and follow specific rules where the first part might oppose the gender of the Ma'dud while the second part matches it.
is a grammatical compound for numbers 11–19 where two digits are fused into a single unit with fixed endings, representing a hidden "and" relationship. used in specific sentence contexts like
: Reviewing this concept requires understanding how the gender and case of the number change based on the noun. For example, numbers 3–10 typically have a "reverse gender" relationship with their Arabic Language Mastery Contextual Usage
(Numerical Phrase). This grammatical construct is responsible for quantifying nouns, bridging the gap between mathematical counting and linguistic expression. 2. Core Components of Tarkib-e-Adadi Tarkib-e-Adadi is noted as a frequent source of error
Despite being called "singular" numbers, this category dictates how basic quantities are phrased. The rules split into two distinct sub-behaviors. Numbers 1 and 2
: In sentence structures, Tarkib Adadi functions as a unified phrase. Understanding these constructions is essential for mastering Arabic syntax ( Nahwu ) and correctly applying diacritical marks ( harakat ).
The grammatical state of the numbered item is also determined by the type of number used.
The grammatical relationship between these two components changes across four specific numerical ranges. These ranges determine whether the ma'dud will function as a descriptive specification ( tamyiz ) or a possessive fraction ( mudhaf ilayh ). Tarkib Adadi is far more than a grammatical oddity
The number 15 in Arabic is Khamsata 'Ashara (خَمْسَةَ عَشَرَ). Structurally, this represents a fusion of Khamsah (five) and 'Asharah (ten), implying "five and ten". Grammatical Parsing (I'rab) of Tarkib Adadi
In classical Arabic syntax, Tarkib Adadi is defined as a compound phrase consisting of two numerical parts where a conjunction particle (specifically the Harf Athf "وَ" meaning "and") is omitted but structurally implied.
The cardinal form represents pure quantity or basic numerical counts. This applies exclusively to numbers from . Numbers 21 through 99 do not fall under Tarkib Adadi because they explicitly retain the conjunction particle (e.g., Wahid wa 'Ishrun ), classifying them instead as Tarkib Athfi (conjunction compounds). 2. Ordinal Form (Al-Adad al-Tartibi)
Why such complexity? The answer lies in Arabic’s preference for conciseness and logical distinction. Tarkib Adadi creates a for the “teens” because these numbers sit at the threshold between simple units and full tens. By fusing them into a single syntactic block, the language avoids the ambiguity that would arise if 11 were treated as “one and ten” as separate entities. The inverted gender rule also serves a cognitive function: it signals to the listener that this is a compound unit, not two separate numbers.
