A verbal noun, traditionally called a maṣdar, packages an action, process, or result as a noun: وصول “arrival,” نوم “sleep,” حكي “talk,” تغيير “change,” and اختيار “choice / choosing.” Weak roots make the contrast between Form I and derived forms especially clear. Form I nouns must often be learned lexically, while derived stems supply much more stable templates. Start with the broader Maṣdar Overview if noun-like syntax is new to you.
English usually builds action nouns with -ing, -al, -tion, or a separate noun, but those choices do not predict the Arabic form. “Arrival” is وصول, “sleep” is نوم, and “forgetting” is نسيان. Treat the Form I maṣdar as a principal part, then use the derived pattern to support—not replace—memory.
Focused map: one root, two event nouns
The root و-ص-ل illustrates both sides of the system. Form I وصل “arrive” has وصول “arrival,” while causative Form II وصّل “deliver / take someone somewhere” has the regular noun توصيل “delivery / transportation.”

توصيل الطلبات بهالمنطقة بياخد وقت.

ṣār fī ittiṣāl bēn esh-shirketēn baʿd el-izhtimēʿ.
There was contact between the two companies after the meeting. (professional; Form VIII maṣdar)
Form I: genuinely lexical choices
There is no single productive Form I maṣdar template, and weak roots do not make one appear. Several high-frequency nouns are short, but others contain an added syllable or preserve a weak radical differently.
| Verb | Maṣdar | Reading | Usual English |
|---|---|---|---|
| قال | قول | ʾawl | saying, statement |
| باع | بيع | bēʿ | sale, selling |
| نام | نوم | nōm | sleep |
| حكى | حكي | ḥake | talk, speaking |
| نسي | نسيان | nisyēn | forgetting, forgetfulness |
| زار | زيارة | ziyāra | visit, visiting |
بيع البيت أخد أكتر من ستة أشهر.
bēʿ el-bēt akhad aktar min sitte ashhur.
The sale of the house took more than six months. (neutral; hollow-root Form I noun)
النوم بكير بيفرق معي تاني نهار.
en-nōm bkīr byifroʾ maʿe tēne nahār.

هالحكي ما بينقال قدام الزبون.
hal-ḥake ma byinʾāl ʾaddēm ez-zabūn.
You don't say that kind of thing in front of the customer. (informal; حكي lexicalized as ‘talk / what was said’)
النسيان طبيعي وقت الواحد يكون تعبان.
en-nisyēn ṭabīʿe waʾet el-wāḥad ykūn taʿbēn.
Forgetfulness is normal when someone is tired. (neutral; final-weak noun with -ان)
زيارتنا كانت قصيرة بس كتير حلوة.
ziyāretna kānet ʾṣīra bass ktīr ḥilwe.
Our visit was short but really nice. (informal; زيارة with possessive suffix)
The hard truth is lexical: the verb alone does not let you calculate نسيان rather than a plausible-looking alternative. Dictionaries and this guide's principal parts are essential.
Derived forms: more stable families
Derived-stem nouns preserve their template even when the root is weak. Form II commonly has تفعيل, Form V has تفعّل, and Form VIII commonly has افتعال. Weakness can affect the spelling inside the template, but the family relationship remains visible.
| Stem | Verb | Maṣdar | Reading |
|---|---|---|---|
| Form II | سمّى “name” | تسمية | tasmiye |
| Form II | غيّر “change” | تغيير | taghyīr |
| Form V | تغيّر “change, become different” | تغيّر | taghayyor |
| Form VIII | اختار “choose” | اختيار | ikhtiyār |
| Form VIII | اتفق “agree” | اتفاق | ittifāʾ |
تسمية الملف بوضوح بتوفر وقت عالفريق.
tasmiyet el-malaf b-wuḍūḥ btwaffer waʾet ʿal-farīʾ.
Naming the file clearly saves the team time. (professional; Form II final-weak maṣdar)
تغيير الموعد بهالسرعة عمل لخبطة.

اختيار الخط المناسب بيسهل القراءة.
ikhtiyār el-khaṭṭ el-mnēseb byisahhel el-ʾirāʾa.

الاتفاق كان واضح من أول يوم.
el-ittifāʾ kān wāḍeḥ min awwal yōm.
The agreement was clear from the first day. (neutral; lexicalized result noun from Form VIII)
These templates are reliable guides, not permission to coin every imaginable noun. Productivity is strongest where the verb itself is established. A form that is morphologically possible may still sound bureaucratic or simply unfamiliar.
These forms behave as nouns
A maṣdar can take the article, an adjective, a possessive suffix, or the first position in an iḍāfa. It can also pluralize when speakers count separate instances or types rather than the activity in general.
التوصيل السريع أغلى بخمسة دولار.
et-tawṣīl es-sarīʿ aghla b-khamse dōlār.
Express delivery costs five dollars more. (commercial; definite noun plus adjective)
صار في اتصالين من الرقم نفسه.
ṣār fī ittiṣālēn min er-raʾam nafso.
There were two calls from the same number. (informal; dual for two separate instances)
عنا تلات اختيارات، وكل واحد إله كلفة مختلفة.
ʿinna tlēt ikhtiyārāt, w-kill wāḥad ilo kilfe mokhtalfe.
We have three options, and each one has a different cost. (neutral; lexicalized count plural)
By contrast, النوم normally names sleep as a mass-like activity and is not casually pluralized. Pluralization belongs to the noun's established meaning, not automatically to its morphological status as a maṣdar.
Register and the verb alternative
Maṣdars are fully normal in speech, but a dense chain of them can sound administrative. Everyday Lebanese often prefers a finite clause where English formal prose prefers nominalization. Compare neutral لما وصل المدير “when the manager arrived” with more report-like بعد وصول المدير “after the manager's arrival.”
بعد وصول المدير بلشنا الاجتماع.
baʿd wuṣūl el-mdīr ballashna l-izhtimēʿ.
After the manager's arrival, we started the meeting. (professional; compact nominal style)
لما وصل المدير بلشنا نحكي بالنقاط الصعبة.
lamma wiṣel el-mdīr ballashna niḥke bin-niʾāṭ eṣ-ṣaʿbe.
When the manager arrived, we started discussing the difficult points. (neutral conversation; finite alternative)
Dialogue: delivery options
قديش كلفة توصيل هالطاولة؟
ʾaddēsh kilfet tawṣīl hal-ṭāwle?
Customer: How much does delivery of this table cost? (informal commercial question)
الكلفة بتتغير حسب وقت الوصول.
el-kilfe btitghayyar ḥasab waʾet el-wuṣūl.
Employee: The cost changes depending on the arrival time. (neutral; derived verb and Form I maṣdar)
طيب، اختياري هو التوصيل العادي.
ṭayyeb, ikhtiyāre huwwe t-tawṣīl el-ʿāde.
Customer: Okay, my choice is standard delivery. (informal; maṣdar with possessive suffix)
Common Mistakes
Inventing a uniform Form I pattern
❌ وصول، نيوم، حكيان كلن عوزن واحد.
Incorrect analysis — weak Form I maṣdars do not share one predictable template.
✅ وصول ونوم وحكي لازم نتعلم كل وحدة مع فعلها.
wuṣūl w-nōm w-ḥake lāzem nitʿallam kill waḥde maʿ fiʿla.
We need to learn وصول, نوم, and حكي individually with their verbs.
Using the finite verb where a noun is required
❌ بعد وصل المدير بلشنا.
Incorrect for ‘after the manager's arrival’ — بعد here selects a noun phrase, not the finite perfect وصل.
✅ بعد وصول المدير بلشنا فورا.
baʿd wuṣūl el-mdīr ballashna fawran.
After the manager's arrival, we started immediately. (professional)
Treating every maṣdar as an uncountable activity
❌ اتصال ما بينعد لأنه مصدر.
Incorrect analysis — a lexicalized maṣdar such as اتصال can count separate calls.
✅ عملت اتصالين، بس ما حدا رد.
ʿmilet ittiṣālēn, bass ma ḥada radd.
I made two calls, but nobody answered.
Overusing nominal style in conversation
❌ بعد قيامي بالوصول، صار إجرائي للاتصال.
Grammatically modeled on heavy formal Arabic, but unnatural for ordinary Beirut conversation.
✅ بس وصلت، اتصلت فيك دغري.
bass wiṣlet, ttaṣalet fīk doghre.
As soon as I arrived, I called you right away. (informal Lebanese)
Key Takeaways
Learn weak Form I maṣdars as principal parts: وصول، قول، بيع، نوم، حكي، نسيان، زيارة. Derived forms are more transparent: توصيل، تسمية، تغيير، اتصال، اختيار. Once formed, a maṣdar is a noun: it can be definite, modified, possessed, counted when its meaning allows, and used in an iḍāfa. Use nominal density deliberately—compact in professional writing, lighter beside finite clauses in conversation.
