A nisba adjective relates something to a place, people, institution, material, or field: مصري “Egyptian,” جامعي “university-related,” حكومي “governmental,” and صيني “Chinese.” The masculine form typically ends in written ـي, the feminine in ـية, and the common human plural in ـيين.
Nisba formation is productive, but the stem is not always predictable. Learn frequent forms as vocabulary, especially nationalities and colloquial-versus-formal alternatives. Once formed, a nisba behaves like an adjective: it follows its noun and agrees in gender, animacy-sensitive number, and definiteness.
Review the ordinary person-group agreement on human plural adjectives.
The basic three-form pattern
| Base | Masculine | Feminine | Human plural |
|---|---|---|---|
| مصر | مصري | مصرية | مصريين |
| الصين | صيني | صينية | صينيين |
| جامعة | جامعي | جامعية | جامعيين |
| ريف | ريفي | ريفية | ريفيين |
طالب مصري وطالبة مصرية وطلبة مصريين.
ṭālib maṣri wi-ṭālba maṣriyya wi-ṭalaba maṣriyyīn.
An Egyptian male student, an Egyptian female student, and Egyptian students.
دكتور جامعي ودكتورة جامعية وأساتذة جامعيين.
doktōr gāmʿi wi-doktōra gāmʿiyya wi-ʾasātza gāmʿiyyīn.
A male university lecturer, a female university lecturer, and university lecturers.
The long sequence ـيين in the plural reflects the nisba stem plus plural ـين. In ordinary Cairene it is pronounced smoothly as -iyyīn, not with an MSA case ending.
The first example is literally ordered “student Egyptian, female student Egyptian, students Egyptian.” Natural English moves Egyptian before each noun; Egyptian keeps the nisba after its head.
Human and nonhuman plurals diverge
A human plural normally takes a plural nisba. A nonhuman plural normally takes feminine singular agreement in the neutral Cairene baseline.
المهندسين المصريين وصلوا بدري.
il-mohandisīn il-maṣriyyīn wiṣlu badri.
The Egyptian engineers arrived early. (human plural)
الأفلام المصرية اتعرضت في المهرجان.
il-ʾaflām il-maṣriyya itʿaraḍit fī l-mahragān.
The Egyptian films were shown at the festival. (nonhuman plural with feminine singular agreement)
The plural noun أفلام does not take human مصريين. Its adjective is feminine singular مصرية, just like other neutral nonhuman-plural agreement.
Spontaneous Egyptian can individualize some nonhuman groups and use plural agreement, unlike the categorical formal-MSA rule. Relational nisbas with ordinary products, films, documents, and institutions nevertheless strongly favor the feminine-singular baseline.
Attributive versus predicative use
Definiteness distinguishes an adjective inside the noun phrase from a predicate.
الفيلم المصري مشهور بره مصر.
il-film il-maṣri mashhūr barra Maṣr.
The Egyptian film is famous outside Egypt.
الفيلم مصري، بس المخرج لبناني.
il-film maṣri, bass il-mokhrig libnāni.
The film is Egyptian, but the director is Lebanese.
In الفيلم المصري, the definite adjective identifies the film’s relation. In الفيلم مصري, bare مصري is the predicate. English uses the same word Egyptian in both, so learners must attend to the article.
Nisbas follow the noun and can stack with qualities
A relational adjective normally comes after the noun. Other adjectives may follow and add quality, age, size, or evaluation.
لقينا مطعم مصري صغير ونضيف.
laʾēna maṭʿam maṣri ṣoghayyar wi-niḍīf.
We found a small, clean Egyptian restaurant.
المستشفى الحكومي الكبير بعيد شوية.
il-mostashfa l-ḥokūmi l-kibīr baʿīd shwayya.
The large government hospital is a little far away.
Both direct modifiers repeat the article in the definite phrase. Bare بعيد remains the predicate.
Relational nisbas are not normally gradable: مصري قوي does not neutrally mean “very Egyptian.” In playful, political, or identity-focused speech, speakers can coerce a degree reading (expressive/informal), but ordinary description uses a separate quality adjective such as مصري أصلي “authentically Egyptian.”
Language names are substantivized nisbas
Bare masculine nisbas commonly name a language or medium after speech verbs: بتكلم عربي “I speak Arabic.” Feminine العربية appears when the understood head is اللغة or when the language itself is a definite topic.
بتكلم عربي وإنجليزي في الشغل.
batkallim ʿarabi wi-ʾingilīzi fish-shoghl.
I speak Arabic and English at work.
اللغة العربية ليها لهجات كتير.
il-logha l-ʿarabiyya līha lahgāt ktīr.
The Arabic language has many dialects.
The article pattern comes from the construction, not from a permanent property of the nisba itself.
Colloquial and formal lexical alternatives
Egyptian sometimes prefers a colloquial nationality form where formal MSA uses another nisba. Mainstream Cairene فرنساوي / فرنساوية / فرنساويين contrasts with formal فرنسي / فرنسية / فرنسيون. Educated speakers may code-switch, and age or professional context can affect the choice.
جارنا فرنساوي وبيتكلم عربي كويس.
gārna faransāwi wi-biyitkallim ʿarabi kwayyis.
Our neighbor is French and speaks Arabic well. (mainstream colloquial lexical choice)
Formal فرنسي is not incorrect; it is a formal/code-switched alternative. Do not mix forms randomly while claiming one uniform register.
A natural descriptive exchange
المطعم ده صيني ولا ياباني؟
il-maṭʿam da ṣīni walla yābāni?
Is this restaurant Chinese or Japanese?
صيني، والشيفات صينيين كمان.
ṣīni, wi-sh-shīfāt ṣīniyyīn kamān.
Chinese, and the chefs are Chinese too.
تمام، نجرب الأكل الصيني هنا.
tamām, nigarrab il-ʾakl iṣ-ṣīni hina.
Great—let’s try the Chinese food here.
The restaurant and food are nonhuman singulars, so صيني is masculine singular. The human chefs take plural صينيين.
Common Mistakes
Putting the nisba before the noun
❌ مصري مطعم قريب.
Incorrect in neutral adjective order—the noun comes first.
✅ مطعم مصري قريب.
maṭʿam maṣri ʾarīb.
A nearby Egyptian restaurant.
Ignoring feminine agreement
❌ بنت مصري بتشتغل معانا.
Incorrect—بنت requires feminine مصرية.
✅ بنت مصرية بتشتغل معانا.
bint maṣriyya bitishtaghal maʿāna.
An Egyptian woman works with us.
Omitting article agreement
❌ المطعم مصري الجديد فتح.
Incorrect for ‘the new Egyptian restaurant’; both direct modifiers must be definite.
✅ المطعم المصري الجديد فتح.
il-maṭʿam il-maṣri l-gidīd fataḥ.
The new Egyptian restaurant opened.
Using the human plural with nonhuman nouns
❌ شفت أفلام مصريين كتير.
Incorrect in the neutral nonhuman-plural pattern.
✅ شفت أفلام مصرية كتير.
shoft ʾaflām maṣriyya ktīr.
I saw many Egyptian films.
Treating the derivation as mechanically predictable
❌ جارنا فرنسياني.
Invented form—the attested nationality adjective must be learned lexically.
✅ جارنا فرنساوي.
gārna faransāwi.
Our neighbor is French. (mainstream colloquial)
Key Takeaways
- The common pattern is masculine ـي, feminine ـية, and human plural ـيين.
- Human plurals take plural nisbas; neutral nonhuman plurals take feminine singular nisbas.
- A definite attributive nisba repeats الـ; a predicate nisba is bare.
- Nisbas follow the noun and are normally relational rather than gradable.
- Formation is only partly productive: learn common stems and register-specific alternatives as vocabulary.
