Coordinating Weak-Verb Forms | Arabic (Modern Standard) Grammar

When two Arabic verbs are coordinated, و، فـ، ثم، أو connect forms that already have tense, mood, and agreement. The conjunction does not repair or regularize a weak stem. Under لن, coordinated verbs are subjunctive; under لم, they are jussive; after a shared أن, a second verb coordinated at the same syntactic level normally matches the first.

English coordination often leaves both verbs in a visibly identical plain form—“will not go or stay.” Arabic can mark the shared dependency twice: in the governing particle and in each verb’s ending. With weak verbs, losing one final letter can be the only visible sign that the coordination is grammatical; the pausal and connected forms explain why that sign is not always audible.

Shared governor, parallel mood

A governor may take a coordinated phrase as its complement. In لن يأتيَ أو يبقى, لن governs both يأتي and يبقى even though it appears only once. In traditional analysis, the second verb receives subjunctive mood by coordination with the first.

Governor	First verb	Coordinated verb	Required relation
لن	يأتيَ	ويبقى	both subjunctive; fatḥa is estimated on final ى in يبقى
لم	يأتِ	ويبقَ	both jussive
أن	نسعى	ونرى	both subjunctive; fatḥa estimated on final ى

The lexical sets matter. Form I أَتَى / يَأْتِي, root أ-ت-ي, is final-weak and hamzated; بَقِيَ / يَبْقَى, root ب-ق-ي, is final-weak; سَعَى / يَسْعَى, root س-ع-ي, and رَأَى / يَرَى, root ر-ء-ي, both end in alif maqṣūra but have different internal histories. Coordination does not make them one paradigm.

لن يأتي المندوب أو يبقى في الفندق الليلة.

lan yaʾtiya l-mandūbu ʾaw yabqā fī l-funduqi l-layla.

The delegate will neither come nor stay at the hotel tonight. (Formal; both verbs are subjunctive.)

لم يأت المندوب ولم يبق أحد في المكتب بعد السادسة.

lam yaʾti l-mandūbu wa-lam yabqa ʾaḥadun fī l-maktabi baʿda s-sādisa.

The delegate did not come, and no one remained in the office after six. (Formal; repeated لم.)

نريد أن نسعى إلى حل عملي ونرى نتائجه قبل نهاية الشهر.

nurīdu ʾan nasʿā ʾilā ḥallin ʿamaliyyin wa-narā natāʾijahu qabla nihāyati sh-shahr.

We want to pursue a practical solution and see its results before the end of the month. (Formal; shared أن.)

Final ى carries an estimated subjunctive fatḥa, so نسعى and نرى look and sound like their indicative forms. The shared أن and parallel syntax—not an invented extra vowel—establish the mood.

💡

Scope first, endings second: bracket لن [يأتي أو يبقى] or أن [نسعى ونرى], then inflect every verb inside the bracket. Do not conjugate only the verb adjacent to the particle.

Repeating the governor makes scope explicit

Arabic permits a shared governor where the structure is clear, but repeating لم، لن، لا is often the better editorial choice (formal). Repetition removes doubt about whether the second verb is coordinated inside the governed phrase or begins a new assertion.

لن تدعو اللجنة الشاهد ولن تعطيه نسخة من الإفادة.

lan tadʿuwa l-lajnatu sh-shāhida wa-lan tuʿṭiyahu nuskhatan mina l-ʾifāda.

The committee will not summon the witness or give him a copy of the statement. (Formal; repeated لن clarifies scope.)

لم يقل المدير ذلك ولم ير الموظفتين بعد الاجتماع.

lam yaquli l-mudīru dhālika wa-lam yara l-muwaẓẓafatayni baʿda l-ijtimāʿ.

The director did not say that and did not see the two employees after the meeting. (Formal.)

Form I hollow قَالَ / يَقُولُ, root ق-و-ل, shortens to jussive يَقُلْ. Before the definite article’s hamzat al-waṣl, connected speech supplies i: يَقُلِ المدير. That i is a boundary vowel, not an indicative ending. Final-weak رَأَى / يَرَى becomes jussive يَرَ. Each verb follows its own verified stem rule under the same repeated governor.

With negation, repetition is especially valuable. لا يدعو المديرُ الضيفَ ويعطيه الملفَّ naturally risks the reading “the director does not invite the guest and [then] gives him the file,” where only the first predicate is clearly negated. لا يدعو... ولا يعطي... places both within negative scope.

لا يدعو هذا النظام المستخدم إلى التسجيل ولا يعطيه سببا للانتظار.

lā yadʿū hādhā n-niẓāmu l-mustakhdima ʾilā t-tasjīli wa-lā yuʿṭīhi sababan lil-intiẓār.

This system neither asks the user to register nor gives them a reason to wait. (Formal.)

Keep person and agreement parallel—unless the subject changes

Coordination normally preserves one understood subject. If the delegates are established before both predicates, both verbs are masculine plural: المندوبون جاءوا وقالوا. In neutral VSO, however, a verb before its overt plural subject usually appears singular, while a later coordinated verb may have the now-established plural subject understood.

جاء المندوبون وقالوا إنهم سيبقون حتى الغد.

jāʾa l-mandūbūna wa-qālū ʾinnahum sayabqawna ḥattā l-ghad.

The delegates came and said that they would remain until tomorrow. (Neutral VSO: singular first verb, then plural coordinated verb.)

رأت الباحثتان الخلل وسعتا إلى إصلاحه قبل نشر النتائج.

raʾati l-bāḥithatāni l-khalala wa-saʿatā ʾilā ʾiṣlāḥihi qabla nashri n-natāʾij.

The two researchers noticed the flaw and sought to fix it before publishing the results. (Formal VSO: singular feminine first verb, dual second verb.)

If the subject genuinely changes, mark that change rather than forcing formal parallelism:

لم تأت المديرة، لكن مساعديها جاؤوا وأعطونا المفاتيح.

lam taʾti l-mudīratu, lākinna musāʿidīhā jāʾū wa-ʾaʿṭawnā l-mafātīḥ.

The director did not come, but her assistants came and gave us the keys. (Neutral MSA.)

Conjunctions, elision, and support vowels

The conjunction وَ is attached in writing. Before a word beginning with hamzat al-waṣl, the initial hamza is not pronounced in connected speech: وَادْعُ is wa-dʿu, وَامْشِ is wa-mshi. The alif stays on the page; elision is phonological, not a spelling deletion.

اتصل بالمكتب وادع الخبيرتين إلى الاجتماع.

ittaṣil bil-maktabi wa-dʿu l-khabīratayni ʾilā l-ijtimāʿ.

Call the office and invite the two women experts to the meeting. (Direct instruction.)

لا تمش خلف الحاجز ولا تسع إلى فتح الباب بالقوة.

lā tamshi khalfa l-ḥājizi wa-lā tasʿa ʾilā fatḥi l-bābi bil-quwwa.

Do not walk behind the barrier or try to force the door open. (Formal warning; two prohibitive jussives.)

Prohibitive لا requires jussive تمشِ and تسعَ. The conjunction contributes no new mood; repeating لا makes both prohibitions unmistakable.

💡

Keep spelling and sound separate at conjunction boundaries: write وادعُ، وامشِ with alif, but elide hamzat al-waṣl after wa-. Never use elision as permission to drop a root letter.

Coordination is not automatic sequence or result

Plain و can leave the temporal relation open. جاء وقال often suggests “came and said,” but و itself does not encode “then.” Use ثم for delayed sequence and فـ for close sequence or consequence when that distinction matters. Some uses of result فـ after requests or negation impose a special subjunctive; that is a separate construction, not ordinary coordination.

دعا الوزير الخبراء، ثم أعطاهم مهلة أسبوع لمراجعة الخطة.

daʿā l-wazīru l-khubarāʾa, thumma ʾaʿṭāhum muhlata ʾusbūʿin limurājaʿati l-khuṭṭa.

The minister invited the experts, then gave them a week to review the plan. (Formal.)

Common Mistakes

Leaving the second verb indicative under a shared governor

❌ لم يأت المندوب ويبقى في الفندق.

Incorrect for two coordinated negated events—يبقى must be jussive يبقَ, or repeat لم for clarity.

✅ لم يأت المندوب ولم يبق في الفندق.

lam yaʾti l-mandūbu wa-lam yabqa fī l-funduq.

The delegate did not come and did not stay at the hotel.

Making only the first predicate negative

❌ لا تدعو اللجنة الشاهد وتعطيه الملف.

Ambiguous—the second verb can sound like a positive new assertion rather than part of the negation.

✅ لا تدعو اللجنة الشاهد ولا تعطيه الملف.

lā tadʿū l-lajnatu sh-shāhida wa-lā tuʿṭīhi l-milaff.

The committee neither summons the witness nor gives him the file.

Regularizing two different weak classes alike

❌ لم يقول المدير ولم يرى الخلل.

Incorrect—قال shortens to يقلْ in the jussive, while رأى becomes يرَ.

✅ لم يقل المدير ذلك ولم ير الخلل.

lam yaquli l-mudīru dhālika wa-lam yara l-khalal.

The director did not say that and did not see the flaw.

Using full plural agreement before an overt plural subject

❌ جاءوا المندوبون وقالوا رأيهم.

Incorrect as neutral VSO—the first verb before the overt plural subject is singular.

✅ جاء المندوبون وقالوا رأيهم.

jāʾa l-mandūbūna wa-qālū raʾyahum.

The delegates came and gave their opinion.

Key Takeaways

A shared governor governs every verb coordinated inside its phrase; each verb still follows its own weak-stem rules.
Repeating لم، لن, or negative لا is often the clearest formal choice.
Preserve person and number across coordinated predicates unless syntax or a changed subject requires different agreement.
Write hamzat al-waṣl after و, but elide it in connected pronunciation.
Do not confuse ordinary coordination with special result-فـ constructions.
