نَامَ-type Hollow Verbs | Arabic (Modern Standard) Grammar

نَامَ / يَنَامُ “sleep, fall asleep” is a Form-I hollow verb from root ن-و-م. Its middle radical is historically و, but it does not follow قَالَ / يَقُولُ. The imperfect has long ā, the suffixed perfect has short i, and the masculine-singular jussive and imperative have short a: نِمْتُ، لَمْ يَنَمْ، نَمْ.

This is the clearest reason not to memorize a rule such as “hollow wāw verbs use ū.” Root class and surface pattern are related, but a Form-I verb’s stem vowels remain lexical. Compare the i-class in the بَاعَ-type lesson, then learn the verified principal parts نَامَ / يَنَامُ / نَوْمٌ and the short stems that appear in governed and suffixed environments.

The vowel map

The diagnostic forms belong together even though they display three different vowels:

Environment	Form	Stem vowel
perfect, 3 m.sg.	نَامَ	long ā
imperfect, 3 m.sg.	يَنَامُ	long ā
maṣdar	نَوْمٌ	diphthong aw
perfect + consonantal suffix	نِمْتُ	short i
jussive, 3 m.sg.	لَمْ يَنَمْ	short a
imperative, 2 m.sg.	نَمْ	short a

The perfect and imperfect happen to share ā, but that does not make them the same tense or aspect. Perfect نام presents a completed sleeping event or entry into sleep; imperfect ينام can describe a habit, an event in progress, or a contextually future event.

نام الطفل بعد أن قرأت له أمه قصة

nāma ṭ-ṭiflu baʿda ʾan qaraʾat lahu ʾummuhu qiṣṣa

The child fell asleep after his mother read him a story. (Formal neutral narration.)

ينام أخي عادة قبل منتصف الليل

yanāmu ʾakhī ʿādatan qabla muntaṣafi l-layl

My brother usually sleeps before midnight. (Formal habitual imperfect.)

نمت في القطار وفاتتني محطتي

nimtu fī l-qiṭāri wafātatnī maḥaṭṭatī

I fell asleep on the train and missed my stop. (Formal.)

💡

Use four checkpoints, not one analogy: نامَ، ينامُ، نِمتُ، لم يَنَمْ. Comparing only نام with قال hides the class difference that controls every shorter form.

The perfect: nām- and nim-

The long stem appears in common third-person forms, while consonant-initial suffixes trigger short nim-:

Subject	Form	Subject	Form
هو	نَامَ	هي	نَامَتْ
هما (m.)	نَامَا	هم	نَامُوا
أنا	نِمْتُ	نحن	نِمْنَا
أنتِ	نِمْتِ	هنّ	نِمْنَ

نامت الطبيبة ساعتين فقط قبل بدء المناوبة

nāmati ṭ-ṭabībatu sāʿatayni faqaṭ qabla badʾi l-munāwaba

The doctor slept for only two hours before her shift began. (Formal.)

نمنا في فندق قريب من المطار

nimnā fī funduqin qarībin mina l-maṭār

We slept in a hotel near the airport. (Formal.)

الممرضات نمن بعد انتهاء المناوبة الليلية

al-mumarriḍātu nimna baʿda ntihāʾi l-munāwabati l-layliyya

The nurses slept after the night shift ended. (Formal SVO; feminine-plural agreement.)

The verb is intransitive. English permits “sleep eight hours,” but Arabic duration is not a direct patient affected by the verb; نام ثماني ساعات uses an adverbial accusative of duration. Locations normally use في “in” or على “on.”

The imperfect and mood

Indicative and subjunctive retain long ā. The masculine-singular jussive shortens it to a:

Environment	Form	Meaning
indicative	يَنَامُ	he sleeps / is sleeping
subjunctive after لن	لَنْ يَنَامَ	he will not sleep
jussive after لم	لَمْ يَنَمْ	he did not sleep
prohibition	لَا تَنَمْ	do not sleep

لن تنام الطفلة بسهولة بعد شرب القهوة

lan tanāma ṭ-ṭiflatu bisuhūlatin baʿda shurbi l-qahwa

The girl will not fall asleep easily after drinking coffee. (Formal; subjunctive after لن.)

لم ينم السائق جيدا في الليلة السابقة

lam yanami s-sāʾiqu jayyidan fī l-laylati s-sābiqa

The driver did not sleep well the previous night. (Formal; jussive after لم.)

The connected reading يَنَمِ السائق includes a linking i to avoid a cluster. The governed form itself is يَنَمْ with short a in the stem and sukūn on م.

For dual and masculine-plural members of the five verbs, mood deletes nūn rather than shortening the long vowel: ينامانِ → لن يناما / لم يناما, ينامونَ → لن يناموا / لم يناموا.

الطفلان لم يناما أثناء الرحلة

aṭ-ṭiflāni lam yanāmā ʾathnāʾa r-riḥla

The two children did not sleep during the trip. (Formal SVO; dual agreement.)

لم ينم الضيوف حتى وقت متأخر

lam yanami ḍ-ḍuyūfu ḥattā waqtin mutaʾakhkhir

The guests did not sleep until late. (Formal VSO; singular verb before an explicit human plural.)

Commands: نَمْ, نَامِي, نَامُوا

The masculine-singular command comes from second-person jussive تَنَمْ after removing تـ: نَمْ. Other addressee forms keep the long vowel before their suffixes: نَامَا، نَامِي، نَامُوا. Feminine plural uses نَمْنَ.

نم مبكرا لأن الاجتماع سيبدأ في السابعة

nam mubakkiran liʾanna l-ijtimāʿa sayabdaʾu fī s-sābiʿa

Go to sleep early because the meeting will start at seven. (One male addressee; formal MSA.)

نامي قليلا قبل أن تبدأ المناوبة

nāmī qalīlan qabla ʾan tabdaʾa l-munāwaba

Sleep a little before the shift begins. (One female addressee; formal MSA.)

ناموا في الغرفة الداخلية بعيدا عن الضوضاء

nāmū fī l-ghurfati d-dākhiliyyati baʿīdan ʿani ḍ-ḍawḍāʾ

Sleep in the inner room, away from the noise. (Male or mixed plural addressees; formal.)

💡

Do not extend singular نَمْ by simple addition. The feminine and masculine-plural commands restore the long stem: نامي، ناموا, while feminine plural is نَمْنَ.

Lexical meaning and complements

Depending on context, نام can focus on the state “sleep” or the transition “fall asleep.” Arabic does not need a separate phrasal verb corresponding to English “fall asleep.” Adverbs and the surrounding event sequence clarify the reading.

كان يقرأ التقرير ثم نام على الأريكة

kāna yaqraʾu t-taqrīra thumma nāma ʿalā l-ʾarīka

He was reading the report, then fell asleep on the sofa. (Formal narration.)

The maṣdar نَوْم means “sleep/sleeping.” It appears in phrases such as قلة النوم “lack of sleep” and وقت النوم “bedtime.” Do not invent a maṣdar by copying a productive pattern from another Form-I verb.

Common Mistakes

Treating نام like قال in the imperfect

❌ ينوم الطفل مبكرا

Incorrect for the Form-I meaning ‘the child sleeps’—the verified imperfect is ينامُ, not ينومُ.

✅ ينام الطفل مبكرا في أيام المدرسة

yanāmu ṭ-ṭiflu mubakkiran fī ʾayyāmi l-madrasa

The child sleeps early on school days.

Using nām- before a consonantal perfect suffix

❌ نامت في القطار

Incorrect if the intended subject is ‘I’—نامت means ‘she slept’; ‘I slept’ is نمتُ with short i.

✅ نمت في القطار عشر دقائق

nimtu fī l-qiṭāri ʿashra daqāʾiq

I slept on the train for ten minutes.

Keeping the long vowel after لم

❌ لم ينام السائق جيدا

Incorrect—لم requires masculine-singular jussive ينمْ.

✅ لم ينم السائق جيدا قبل الرحلة

lam yanami s-sāʾiqu jayyidan qabla r-riḥla

The driver did not sleep well before the trip.

Adding an alif to the singular command

❌ أنام الآن

Incorrect as ‘sleep now’—the command is نمْ; أنام means ‘I sleep.’

✅ نم الآن وسأوقظك في السادسة

nami l-ʾāna wasaʾūqiẓuka fī s-sādisa

Sleep now, and I will wake you at six.

Giving a postverbal plural subject full agreement

❌ ناموا الأطفال في السيارة

Incorrect in neutral formal VSO—use singular نام before the explicit human plural subject.

✅ نام الأطفال في السيارة خلال الرحلة

nāma l-ʾaṭfālu fī s-sayyārati khilāla r-riḥla

The children slept in the car during the trip.

Key Takeaways

نَامَ / يَنَامُ / نَوْمٌ belongs to root ن-و-م, but it is not the قال / يقول vowel class.
The suffixed perfect has short i: نِمْتُ، نِمْنَا، نِمْنَ.
The singular jussive and imperative have short a: لَمْ يَنَمْ، نَمْ.
Feminine and masculine-plural commands restore long ā: نامي، ناموا.
نام is intransitive; use prepositions for place and an adverbial expression for duration.
