Possessive Pronoun Suffixes on Nouns | Arabic (Modern Standard) Grammar

Modern Standard Arabic normally expresses English possessives such as my, your, and their by attaching a pronoun suffix directly to the possessed noun: كتاب “a book” becomes كتابي “my book” and كتابها “her book.” The order is therefore the reverse of English: Arabic literally builds “book-her,” not “her book.”

This suffix does more than abbreviate an independent pronoun. It occupies the second slot of an iḍāfa, the Arabic possessive construction, and makes the whole noun phrase definite. Its exact form is selected by the possessor's person, gender, and number, while the noun remains the grammatical head.

The complete suffix set

The table uses كتاب “book” as the host. The case vowel before most suffixes can change with the noun's role; the forms shown are nominative citation examples.

Possessor	Suffix	Example	Reading	Meaning
I	ـي	كتابي	kitābī	my book
you, masculine singular	ـكَ	كتابك	kitābuka	your book
you, feminine singular	ـكِ	كتابك	kitābuki	your book
he / it, masculine	ـهُ	كتابه	kitābuhu	his/its book
she / it, feminine	ـها	كتابها	kitābuhā	her/its book
we	ـنا	كتابنا	kitābunā	our book
you two	ـكما	كتابكما	kitābukumā	your book
they two	ـهما	كتابهما	kitābuhumā	their book
you, masculine plural	ـكم	كتابكم	kitābukum	your book
you, feminine plural	ـكنّ	كتابكن	kitābukunna	your book
they, masculine plural	ـهم	كتابهم	kitābuhum	their book
they, feminine plural	ـهنّ	كتابهن	kitābuhunna	their book

Written كتابك is ambiguous without short vowels: it can mean “your book” to one man or to one woman. In careful speech, however, -ka and -ki remain distinct.

وجدت مفاتيحك يا سامر.

wajadtu mafātīḥaka yā sāmir.

I found your keys, Samer. (Addressing one man.)

وجدت مفاتيحك يا مريم.

wajadtu mafātīḥaki yā maryam.

I found your keys, Maryam. (Addressing one woman.)

💡

Learn every second-person suffix with its vowel: masculine singular -ka, feminine singular -ki. Ordinary Arabic spelling hides that contrast, but formal pronunciation and meaning do not.

Why the suffix makes the noun definite

An attached possessor identifies the noun just as a definite second term identifies an iḍāfa. Consequently, كتابي means “my book,” not “a book of mine” by default. Do not add the definite article to the possessed noun, and do not add tanwīn.

كتابي الجديد على الطاولة.

kitābiya l-jadīdu ʿalā ṭ-ṭāwila(h).

My new book is on the table.

The adjective is definite because كتابي is definite. The linking -ya heard before الـ belongs to the careful pronunciation of first-person ـي in this connected environment; the spelling remains كتابي.

Compare a predicative possession with an attached possessive. They answer different questions:

هذا الكتاب لها.

hādhā l-kitābu lahā.

This book is hers.

هذا كتابها.

hādhā kitābuhā.

This is her book.

In لها, the prepositional phrase predicates ownership of an already identified book. In كتابها, the suffix is inside the noun phrase and directly identifies the possessor. English can use an independent possessive “hers,” but Arabic does not detach ها and use it as a free word.

Case remains before the suffix

A suffixed noun still carries case, although the ending appears immediately before the suffix. With ـه, for example, careful pronunciation distinguishes nominative كتابُهُ, accusative كتابَهُ, and genitive كتابِهِ. The ordinary spelling كتابه leaves all three readings implicit.

وصل كتابه إلى المكتب.

waṣala kitābuhu ʾilā l-maktab.

His book arrived at the office. (Nominative subject.)

قرأت كتابه في القطار.

qaraʾtu kitābahu fī l-qiṭār.

I read his book on the train. (Accusative object.)

تحدثنا عن كتابه بعد الاجتماع.

taḥaddathnā ʿan kitābihi baʿda l-ijtimāʿ.

We talked about his book after the meeting. (Genitive after a preposition.)

The -hi in the last example is not a different possessor. The third-person masculine suffix harmonizes after i or y; Third-Person ـه and Vowel Harmony treats that alternation in detail.

Changes to the noun host

The suffix joins the noun as part of one written word. A final ة is pronounced -at- before it because tāʾ marbūṭa is no longer at pause:

سيارتنا أمام المبنى.

sayyāratunā ʾamāma l-mabnā.

Our car is in front of the building.

Dual nouns and sound masculine plurals lose their final ن before any possessive suffix. This is the same nūn loss seen before the second term of an iḍāfa.

Unsuffixed form	With suffix	Meaning
طالبانِ	طالباها	her two students (nominative)
طالبَيْنِ	طالبيها	her two students (accusative/genitive)
مهندسونَ	مهندسوهم	their engineers (nominative)
مهندسينَ	مهندسيهم	their engineers (accusative/genitive)

وصل مهندسوها صباحا.

waṣala muhandisūhā ṣabāḥā.

Her engineers arrived in the morning.

The lost nūn is grammatical, not optional spelling. It signals that the suffix has made the noun the first term of a possessive construction.

Subjects, antecedents, and resumptives

A possessive suffix does not serve as the clause's subject. Arabic may omit an independent subject pronoun because a finite verb already marks its subject, but that is a separate fact:

راجعت تقريرك وأرسلت ملاحظاتي.

rājaʿtu taqrīraka wa-ʾarsaltu mulāḥaẓātī.

I reviewed your report and sent my notes. (The verbs themselves mark ‘I.’)

Possessive suffixes also track antecedents. In a relative clause where the relationship is “whose,” formal Arabic normally keeps a resumptive suffix inside the clause:

اتصلت بالشركة التي قابلت مديرها أمس.

ʾittaṣaltu bi-sh-sharikati llatī qābaltu mudīrahā ʾams.

I contacted the company whose director I met yesterday.

Here ها in مديرها points back to feminine الشركة. English leaves a gap after “whose”; Arabic explicitly marks the possessive relationship. A left-dislocated topic works similarly:

هذا التقرير، قرأت مقدمته فقط.

hādhā t-taqrīru, qaraʾtu muqaddimatahu faqaṭ.

As for this report, I read only its introduction.

💡

A suffix needs a clear antecedent. If two masculine singular nouns are equally available, ـه may be grammatically correct but communicatively unclear; repeat the noun when the intended possessor is not obvious.

Common Mistakes

Losing second-person gender

❌ هل هذا هاتفك يا ليلى؟

hal hādhā hātifuka yā laylā?

Incorrect reading — one woman requires the feminine suffix vowel -ki.

✅ هل هذا هاتفك يا ليلى؟

hal hādhā hātifuki yā laylā?

Is this your phone, Layla?

Writing the suffix as a separate word

❌ هذا كتاب ها.

Incorrect — the possessive suffix is attached directly to its noun.

✅ هذا كتابها.

hādhā kitābuhā.

This is her book.

Copying English possessor order

❌ ها كتاب على المكتب.

Incorrect — Arabic cannot put the bound suffix before the noun like English ‘her book.’

✅ كتابها على المكتب.

kitābuhā ʿalā l-maktab.

Her book is on the desk.

Omitting the resumptive possessive

❌ هذه هي الشركة التي قابلت المدير.

Incorrect for ‘the company whose director I met’ — the relative clause needs a suffix linking the director to the company.

✅ هذه هي الشركة التي قابلت مديرها.

hādhihi hiya sh-sharikatu llatī qābaltu mudīrahā.

This is the company whose director I met.

Leaving an ambiguous antecedent

❌ تحدث سامر مع خالد عن مشروعه.

Potentially unclear — mashrūʿihi can mean Samer's project or Khalid's project.

✅ تحدث سامر مع خالد عن مشروع خالد.

taḥaddatha sāmirun maʿa khālidin ʿan mashrūʿi khālid.

Samer spoke with Khalid about Khalid's project.

Key Takeaways

Attach the suffix to the possessed noun: كتابها, not a separate ها.
Choose the suffix for person, gender, and number; spoken -ka and -ki distinguish the two singular addressees.
A possessive suffix makes its noun definite, removes tanwīn, and triggers nūn loss on duals and sound masculine plurals.
The noun's case appears before the suffix, and tāʾ marbūṭa is pronounced t when a suffix follows.
Relative and topicalized structures often need an overt resumptive suffix, and that suffix must have a clear antecedent.
