Form II is built by doubling the second root consonant: the sound-root pattern is فَعَّلَ / يُفَعِّلُ / تَفْعِيلٌ. The shadda is grammatical structure, not optional pronunciation. It often adds causative force (“make someone do/be”), intensity or repetition, or a verb derived from a noun. Yet these are tendencies, not automatic translations: سلّم can mean “hand over,” “greet,” or “concede,” depending on its complements and context.
English speakers should learn each Form II lexeme through verified principal parts and valency. The pattern helps recognize and conjugate a word after it has been identified; it does not authorize inventing a Form II verb from any root or guessing its exact meaning.
This contrasts with the several lexical stem-vowel classes of Form I, but both Forms still require verified principal parts.
The sound-root pattern
Use عَلَّمَ / يُعَلِّمُ / تَعْلِيمٌ “teach,” root ع-ل-م. Its middle radical ل is doubled throughout the finite stem and appears with shadda in vocalized writing.
| Environment | Form | Function |
|---|---|---|
| active perfect, 3 m.sg. | عَلَّمَ | he taught |
| active imperfect, 3 m.sg. | يُعَلِّمُ | he teaches / is teaching |
| after لن | لَنْ يُعَلِّمَ | he will not teach |
| after لم | لَمْ يُعَلِّمْ | he did not teach |
| imperative, m.sg. | عَلِّمْ | teach! |
| maṣdar | تَعْلِيمٌ | teaching / education |
| active participle | مُعَلِّمٌ | teacher / teaching |
| passive participle | مُعَلَّمٌ | taught / marked |
علمت المدربة الموظفتين طريقة استخدام النظام
ʿallamati l-mudarribatu l-muwaẓẓafatayni ṭarīqata stikhdāmi n-niẓām
The trainer taught the two female employees how to use the system. (Formal; two objects/complements.)
يعلم المدرسون الجدد الطلاب في مجموعات صغيرة
yuʿallimu l-mudarrisūna l-jududu ṭ-ṭullāba fī majmūʿātin ṣaghīra
The new teachers teach the students in small groups. (Formal VSO; singular verb before a human plural subject.)
لن يعلمن هذه الوحدة قبل مراجعة الدرس السابق
lan yuʿallimna hādhihi l-waḥdata qabla murājaʿati d-darsi s-sābiq
They (f.) will not teach this unit before reviewing the previous lesson. (Formal; feminine-plural subjunctive is unchanged.)
Causative meaning is common, not guaranteed
Form I عَلِمَ / يَعْلَمُ means “know”; Form II عَلَّمَ / يُعَلِّمُ means “teach,” conceptually “cause someone to know.” This transparent relationship is important, but not every Form II has a common corresponding Form I, and multiple derived Forms can compete for causative meanings.
علمت ليلى بالقرار صباحا، ثم علمت فريقها الإجراءات الجديدة
ʿalimat laylā bil-qarāri ṣabāḥan, thumma ʿallamat farīqahā l-ʾijrāʾāti l-jadīda
Layla learned of the decision in the morning, then taught her team the new procedures. (Formal Form I/Form II contrast.)
فرح الطفل بخبر نجاحه، ثم فرحته أمه بهدية صغيرة
fariḥa ṭ-ṭiflu bikhabari najāḥihi, thumma farraḥathu ʾummuhu bihadiyyatin ṣaghīra
The child was delighted by the news of his success, then his mother made him happy with a small gift. (Formal Form I/Form II contrast.)
Form I فَرِحَ / يَفْرَحُ “be glad” and Form II فَرَّحَ / يُفَرِّحُ “make glad,” root ف-ر-ح, demonstrate a real causative relationship. Speakers still choose among attested lexical alternatives—Form IV أفرح is also standard here—and the existence of a Form I verb does not make every imagined doubled derivative acceptable.
Intensity, repetition, and distribution
From Form I كَسَرَ / يَكْسِرُ “break,” Form II كَسَّرَ / يُكَسِّرُ / تَكْسِيرٌ often suggests breaking thoroughly, repeatedly, or into pieces. قَطَّعَ / يُقَطِّعُ / تَقْطِيعٌ “cut up” similarly profiles repeated or distributed cutting. Context, not the pattern alone, determines whether an intensive nuance is prominent.
كسر العامل الصندوق القديم ليفصل الخشب عن المعدن
kassara l-ʿāmilu ṣ-ṣundūqa l-qadīma liyafṣila l-khashaba ʿani l-maʿdin
The worker broke up the old box to separate the wood from the metal. (Formal; thorough/distributive reading.)
قطعي الخضراوات إلى قطع صغيرة قبل إضافتها إلى الحساء
qaṭṭiʿī l-khuḍrawāti ʾilā qiṭaʿin ṣaghīratin qabla ʾiḍāfatihā ʾilā l-ḥasāʾ
Cut the vegetables into small pieces before adding them to the soup. (Formal instruction to one woman.)
وزعوا النسخ على المشاركين قبل بدء الجلسة
wazziʿū n-nusakha ʿalā l-mushārikīna qabla badʾi l-jalsa
Distribute the copies to the participants before the session begins. (Formal instruction to a male or mixed group.)
Form II وَزَّعَ / يُوَزِّعُ / تَوْزِيعٌ, root و-ز-ع, lexicalizes distribution. Translating it as merely “intensive wazaʿa” would obscure the verb learners actually need.
Denominative and lexicalized Form II verbs
Form II can create or lexicalize an activity associated with a noun: رَقَّمَ / يُرَقِّمُ / تَرْقِيمٌ “number, paginate,” from the root behind رقم “number”; نَظَّمَ / يُنَظِّمُ / تَنْظِيمٌ “organize,” related to نظام “order/system.” These relationships help memory, but the exact meaning and complement structure remain dictionary facts.
رقم الفريق جميع الصفحات قبل تصوير الوثيقة
raqqama l-farīqu jamīʿa ṣ-ṣafaḥāti qabla taṣwīri l-wathīqa
The team numbered every page before copying the document. (Formal.)

naẓẓamati l-bāḥithatāni l-muqābalāti biḥasabi tārīkhi ʾijrāʾihā
The two female researchers organized the interviews by date. (Formal; feminine-singular verb before a dual subject.)
حَدَّثَ / يُحَدِّثُ / تَحْدِيثٌ, root ح-د-ث, means “update” in technological contexts and “tell/speak to” in other complement frames. A pattern label cannot choose between them.
حدث المهندس البرنامج، ثم حدث زملاءه عن سبب العطل
ḥaddatha l-muhandisu l-barnāmaja, thumma ḥaddatha zumalāʾahu ʿan sababi l-ʿuṭl
The engineer updated the program, then told his colleagues about the cause of the fault. (Formal; two lexical uses.)
Passive and agreement
The Form II passive keeps the doubled middle radical but changes the stem vowels: perfect عُلِّمَ, imperfect يُعَلَّمُ. In neutral VSO, a verb before an explicit human plural subject is singular, while gender remains visible. Non-human plurals normally take feminine-singular agreement.
درب المتطوعون على استخدام أجهزة الإطفاء
durriba l-mutaṭawwiʿūna ʿalā stikhdāmi ʾajhizati l-ʾiṭfāʾ
The volunteers were trained to use the fire extinguishers. (Formal passive VSO; singular masculine verb.)
دربت المتطوعات على الإسعافات الأولية
durribati l-mutaṭawwiʿātu ʿalā l-ʾisʿāfāti l-ʾawwaliyya
The female volunteers were trained in first aid. (Formal passive VSO; singular feminine verb.)
تحدث الأنظمة تلقائيا في منتصف الليل
tuḥaddathu l-ʾanẓimatu tilqāʾiyyan fī muntaṣafi l-layl
The systems are updated automatically at midnight. (Formal; non-human plural with feminine-singular passive.)
Final-weak and hamzated Form II
Final-weak سَمَّى / يُسَمِّي / تَسْمِيَةٌ “name,” root س-م-و, ends in alif maqṣūra in the perfect but yāʾ in the imperfect. Its masculine-singular command is سَمِّ, subjunctive لن يسمّيَ, and jussive لم يسمِّ.
سمت اللجنة المشروع مبادرة المدن الخضراء
sammati l-lajnatu l-mashrūʿa mubādarata l-muduni l-khaḍrāʾ
The committee named the project ‘Green Cities Initiative.’ (Formal; final alif disappears before the suffix.)
لم يسم الباحثان الملف حتى اتفقا على عنوانه
lam yusammi l-bāḥithāni l-malaffa ḥattā ttafaqā ʿalā ʿunwānih
The two researchers did not name the file until they agreed on its title. (Formal VSO; jussive final-weak stem.)
Hamzated هَيَّأَ / يُهَيِّئُ / تَهْيِئَةٌ “prepare,” root ه-ي-أ, keeps the middle-radical doubling while hamza takes the seat required by its vowels.
هيأت المديرة القاعة لاستقبال الضيوف
hayyaʾati l-mudīratu l-qāʿata listiqbāli ḍ-ḍuyūf
The director prepared the hall to receive the guests. (Formal.)
Common Mistakes
Dropping the middle-radical gemination
❌ علم المدرس الطلاب القاعدة
Incorrect if علم is read ʿalima ‘knew’; ‘taught’ is Form II علّم with doubled ل.
✅ علم المدرس الطلاب القاعدة بأمثلة واضحة
ʿallama l-mudarrisu ṭ-ṭullāba l-qāʿidata biʾamthilatin wāḍiḥa
The teacher taught the students the rule with clear examples.
Treating causative meaning as automatic
❌ كل فعل على وزن فعل يعني جعل شخص يفعل
Incorrect—Form II has causative, intensive, denominative, and lexicalized meanings; the lexeme must be verified.
✅ تعني عبارة سلم الرسالة هنا أنه نقلها إلى شخص آخر
taʿnī ʿibāratu sallama r-risālata hunā ʾannahu naqalahā ʾilā shakhsin ʾākhar
Here, the phrase سلّم الرسالة means that he handed the message to another person.
Keeping indicative nūn after لن
❌ لن يسلمون النسخ اليوم
Incorrect—the five verbs delete nūn after لن: يسلموا.
✅ لن يسلموا النسخ قبل توقيع المدير
lan yusallimū n-nusakha qabla tawqīʿi l-mudīr
They will not hand over the copies before the director signs.
Regularizing a final-weak jussive
❌ لم يسمي الباحث الملف
Incorrect—final-weak يسمّي loses final yāʾ in the jussive: لم يسمِّ.
✅ لم يسم الباحث الملف بعد
lam yusammi l-bāḥithu l-malaffa baʿd
The researcher has not named the file yet.
Using plural agreement before an explicit plural subject
❌ نظموا الموظفون الملفات
Incorrect in neutral VSO—the preverbal verb is singular: نظم الموظفون.
✅ نظم الموظفون الملفات بحسب الموضوع
naẓẓama l-muwaẓẓafūna l-malaffāti biḥasabi l-mawḍūʿ
The employees organized the files by topic.
Key Takeaways
- Sound Form II uses فَعَّلَ / يُفَعِّلُ / تَفْعِيلٌ and preserves middle-radical gemination.
- Causative, intensive, and denominative meanings are common tendencies, never automatic translations.
- Learn each verb’s attested meanings and complement frames.
- Passive فُعِّلَ / يُفَعَّلُ retains shadda and follows ordinary Arabic agreement rules.
- Final-weak and hamzated verbs reshape the pattern predictably only after their root class and principal parts are known.
