Arabic participles are verbal adjectives and nouns: they can describe someone or something, agree with a noun, or head a noun phrase while retaining a verb's complements. Weak verbs use the same active and passive participial functions as sound verbs, but their surface forms reflect the location of و or ي in the root. Compare Form-I قَالَ / يَقُولُ / قَوْلًا “say,” root ق-و-ل, whose active participle is قَائِل; بَاعَ / يَبِيعُ / بَيْعًا “sell,” root ب-ي-ع, whose passive participle is مَبِيع; and دَعَا / يَدْعُو / دَعْوَةً, root د-ع-و, whose indefinite nominative active participle is دَاعٍ.
Those three shapes come from three different mechanisms: a hollow active participle develops hamza, a hollow passive participle contracts its middle sequence, and a final-weak active participle declines as a defective noun. Learn the verified participle with the perfect, imperfect, and weak maṣdar rather than trying to recover it from an English translation. The separate passive-participle guide explains the syntax shared by sound and weak passive participles.
Hollow active participles: why قال gives قائل
The ordinary Form-I active-participle frame is فَاعِل. When the middle radical is weak, the long ā of the frame and the weak radical do not remain side by side. The resulting standard form contains hamza: قَائِل “saying; speaker” from قال, بَائِع “selling; seller” from باع, and سَائِر “going; proceeding” from سار / يسير, root س-ي-ر. The hamza is a real written consonant on ئ, not an optional pronunciation mark.
| Principal parts | Active participle | Feminine | Sound masculine plural |
|---|---|---|---|
| قَالَ / يَقُولُ / قَوْلًا | قَائِل | قَائِلَة | قَائِلُونَ / قَائِلِينَ |
| بَاعَ / يَبِيعُ / بَيْعًا | بَائِع | بَائِعَة | بَائِعُونَ / بَائِعِينَ |
| سَارَ / يَسِيرُ / سَيْرًا | سَائِر | سَائِرَة | سَائِرُونَ / سَائِرِينَ |
Once formed, these words decline and agree like ordinary adjectives or nouns. A predicate participle can describe a present state or an intended/imminent action; context supplies the time more strongly than the participle itself. English speakers should not equate it automatically with an English -ing form.
المتحدثة قائلة الحق بوضوح، حتى لو أغضب ذلك بعض الحاضرين.
al-mutaḥaddithatu qāʾilatun l-ḥaqqa biwuḍūḥin, ḥattā law ʾaghḍaba dhālika baʿḍa l-ḥāḍirīn.
The speaker is telling the truth clearly, even if that angers some attendees. (Formal; the active participle governs an accusative object.)
البائعان قائمان عند المدخل، وهما بائعان معتمدان لدى الشركة.
al-bāʾiʿāni qāʾimāni ʿinda l-madkhali, wa-humā bāʾiʿāni muʿtamadāni ladā sh-sharika.
The two sellers are standing at the entrance, and they are authorized vendors for the company.
قال الخبيران إنهما غير قائلين بهذا الرأي في التقرير النهائي.
qāla l-khabīrāni ʾinnahumā ghayru qāʾilayni bihādhā r-raʾyi fī t-taqrīri n-nihāʾiyy.
The two experts said that they did not endorse this view in the final report. (Formal; قائل بـ means ‘holding or maintaining a view.’)
The last example also shows lexical valency. قَائِلٌ بِرَأْيٍ “one who holds a view” keeps بـ, while قَائِلُ الحقيقةِ places the participle's semantic object in a genuine iḍāfa, where الحقيقةِ is genitive rather than accusative. A participle does not erase the complement frame of its verb.
Hollow passive participles: مبيع is not a finite passive
The Form-I passive-participle baseline is مَفْعُول. Hollow roots contract inside it. Root ب-ي-ع gives مَبِيع “sold; for sale,” while root ق-و-ل gives مَقُول “said; statement.” The two roots do not collapse to one vowel: learn مبيع with باع / يبيع and مقول with قال / يقول.
هذا الجهاز مبيع بضمان لمدة سنتين، وليس مستعملا.
hādhā l-jihāzu mabīʿun biḍamānin limuddati sanatayni, wa-laysa mustaʿmalan.
This device is sold with a two-year warranty and is not used.
السيارتان مبيعتان بالفعل، لكن نقل الملكية لم يكتمل بعد.
as-sayyāratāni mabīʿatāni bil-fiʿli, lakinna naqla l-milkiyyati lam yaktamil baʿd.
The two cars have already been sold, but the transfer of ownership is not yet complete.
راجعت المحررتان كل قول منقول، وحذفتا الكلام غير المقول في التسجيل.
rājaʿati l-muḥarriratāni kulla qawlin manqūlin, wa-ḥadhafatā l-kalāma ghayra l-maqūli fī t-tasjīl.
The two editors checked every quoted statement and removed words that were not said in the recording. (Formal.)
The participle agrees with the noun it describes: جهاز مبيع، سيارة مبيعة، سيارتان مبيعتان. By contrast, the finite passive reports an event and has its own verbal agreement: بِيعت السيارتان “the two cars were sold.” English uses sold in both structures, so English form alone cannot tell you whether Arabic needs مبيع or بيع.
بيعت السيارتان أمس، وهما الآن مبيعتان رسميا.
bīʿati s-sayyāratāni ʾamsi, wa-humā l-ʾāna mabīʿatāni rasmiyyan.
The two cars were sold yesterday, and they are now officially recorded as sold.
Final-weak active participles: the case system of داعٍ
Form-I دَعَا / يَدْعُو / دَعْوَةً, root د-ع-و, has active participle دَاعٍ “caller; advocate; someone inviting.” Its underlying stem ends in -ī, so it behaves as an indefinite defective noun (اسم منقوص). In the indefinite nominative and genitive, final ي is omitted in ordinary spelling and the word takes kasr tanwīn: دَاعٍ. In the indefinite accusative, the yāʾ remains: دَاعِيًا. With الـ or in construct, the yāʾ also remains: nominative and genitive have an estimated ending (الدَّاعِي، دَاعِي السَّلَامِ), while accusative fatḥa is audible (رَأَيْتُ الدَّاعِيَ، رَأَيْتُ دَاعِيَ السَّلَامِ).
| Environment | Form | Example role |
|---|---|---|
| indefinite nominative | دَاعٍ | جَاءَ دَاعٍ “an advocate came” |
| indefinite genitive | دَاعٍ | مَعَ دَاعٍ “with an advocate” |
| indefinite accusative | دَاعِيًا | قَابَلْتُ دَاعِيًا “I met an advocate” |
| definite, nominative/genitive | الدَّاعِي | الدَّاعِي / إِلَى الدَّاعِي |
| definite accusative | الدَّاعِيَ | قَابَلْتُ الدَّاعِيَ |
| construct | دَاعِي السَّلَامِ | “the advocate of peace” |
وصل من كل مؤسسة داع إلى الحوار.
waṣala min kulli muʾassasatin dāʿin ʾilā l-ḥiwār.
An advocate of dialogue arrived from each institution. (Formal; indefinite nominative داعٍ.)
تحدثت الصحفية مع داع إلى الإصلاح الإداري.
taḥaddathati ṣ-ṣaḥafiyyatu maʿa dāʿin ʾilā l-ʾiṣlāḥi l-ʾidāriyy.
The journalist spoke with an advocate of administrative reform. (Formal; indefinite genitive داعٍ.)
استضاف البرنامج داعيا إلى حماية الصحفيين.
istaḍāfa l-barnāmaju dāʿiyan ʾilā ḥimāyati ṣ-ṣaḥafiyyīn.
The program hosted an advocate for protecting journalists. (Formal; indefinite accusative داعيًا.)
وصلت الداعية إلى الحوار، ثم قدمت مقترحين عمليين.
waṣalati d-dāʿiyatu ʾilā l-ḥiwāri, thumma qaddamat muqtaraḥayni ʿamaliyyayn.
The woman advocating dialogue arrived and then presented two practical proposals.
The feminine دَاعِيَة retains its yāʾ, while the sound masculine plural has its own contracted forms دَاعُونَ / دَاعِينَ rather than the singular دَاعٍ / دَاعِيًا case alternation. This is nominal inflection, not a tense change. The finite imperfect remains يَدْعُو in the indicative, لَنْ يَدْعُوَ in the subjunctive, and لَمْ يَدْعُ in the jussive.
الناشطان داعيان إلى التهدئة، ولن يدعوا إلى أي تصعيد.
an-nāshiṭāni dāʿiyāni ʾilā t-tahdiʾati, wa-lan yadʿuwā ʾilā ʾayyi taṣʿīd.
The two activists advocate de-escalation, and they will not call for any escalation. (Participle versus subjunctive finite verb.)
Common Mistakes
Preserving the hollow radical instead of writing hamza
❌ المتحدث قايل إن الخطة قابلة للتنفيذ.
Incorrect in formal MSA—the active participle of قال is قائل, with hamza on ي.
✅ المتحدث قائل إن الخطة قابلة للتنفيذ.
al-mutaḥaddithu qāʾilun ʾinna l-khuṭṭata qābilatun lit-tanfīdh.
The speaker says that the plan is feasible. (Formal.)
Regularizing مبيع as مبيوع
❌ الجهاز مبيوع بضمان سنتين.
Incorrect in standard formal Arabic—the verified passive participle of باع is مبيع.
✅ الجهاز مبيع بضمان لمدة سنتين.
al-jihāzu mabīʿun biḍamānin limuddati sanatayn.
The device is sold with a two-year warranty.
Keeping yāʾ in indefinite nominative داعٍ
❌ حضر داعي إلى المصالحة.
Incorrect for an indefinite nominative singular—the defective noun drops ي and takes kasr tanwīn: داعٍ.
✅ حضر داع إلى المصالحة.
ḥaḍara dāʿin ʾilā l-muṣālaḥa.
An advocate of reconciliation attended.
Deleting yāʾ where the accusative requires it
❌ استضاف المؤتمر داع إلى الإصلاح.
Incorrect—the indefinite direct object is accusative داعيًا, whose spelling retains ي and tanwīn fatḥ.
✅ استضاف المؤتمر داعيا إلى الإصلاح.
istaḍāfa l-muʾtamaru dāʿiyan ʾilā l-ʾiṣlāḥ.
The conference hosted an advocate of reform.
Losing dual agreement on a predicate participle
❌ الخبيرتان قائلة بالحاجة إلى مراجعة إضافية.
Incorrect—an adjectival predicate agrees with the dual feminine subject: قائلتان.
✅ الخبيرتان قائلتان بالحاجة إلى مراجعة إضافية.
al-khabīratāni qāʾilatāni bil-ḥājati ʾilā murājaʿatin ʾiḍāfiyya.
The two women experts maintain that an additional review is needed. (Formal.)
Key Takeaways
- Hollow Form-I active participles create hamza: قال → قائل، باع → بائع.
- Hollow passive participles must be learned by root: باع → مبيع, but قال → مقول.
- Final-weak داعٍ is a defective noun: indefinite nominative/genitive lose yāʾ, while داعيًا، الداعي, and construct داعي... retain it.
- Participles agree as nouns and adjectives, retain lexical complements, and do not by themselves encode one English tense.
