Hollow Verbs: Middle Radical و or ي | Arabic (Egyptian) Grammar

A hollow verb has و or ي as its middle historical root consonant. In actual Cairene forms, that radical often appears through a long vowel or a short-vowel alternation rather than as a stable consonant: قال / قلت / بيقول ʾāl / ʾolt / biyʾūl, “said / I said / says.” The label explains why the stems alternate; it does not tell you which vowels a new verb has.

The essential habit is to learn at least three principal parts: third-person masculine perfect, suffixed perfect, and b-imperfect. The weak-root overview explains how these forms reveal the root; this page focuses on using the finite verb.

Diagnostic 1: store the type, not merely the spelling قال

The three high-value types differ in both the suffixed perfect and imperfect. Their visible ا in the citation form is not the middle radical itself.

Type	3rd masc. perfect	1st/2nd perfect	B-imperfect	Imperative
قال-type	قَالْ ʾāl	قُلْتْ ʾolt	بِيِقُولْ biyʾūl	قُولْ ʾūl
باع-type	بَاعْ bāʿ	بِعْتْ biʿt	بِيِبِيعْ biyibīʿ	بِيعْ bīʿ
نام-type	نَامْ nām	نِمْتْ nimt	بِيِنَامْ biyinām	نَامْ nām

The differences are not cosmetic. نومت nawwimt belongs to a different causative verb, “I put someone to sleep”; it cannot replace نمت “I slept.” Likewise, building بقول or بننام requires the particular imperfect stem, not a generic weak-verb formula.

قلتله يستنى عند الباب

ʾoltillu yistanna ʿand il-bāb

I told him to wait by the door. (informal)

بعت العربية عشان مش بستعملها

biʿt il-ʿarabiyya ʿashān mish bastaʿmilha

I sold the car because I don't use it. (informal)

نمت بدري امبارح

nimt badri imbāriḥ

I went to sleep early yesterday. (informal)

💡

Write a hollow verb in your notes as a three-part entry: قال–قلت–بيقول, باع–بعت–بيبيع, نام–نمت–بينام. The citation form alone hides the contrast that matters most.

Diagnostic 2: know which perfect persons use which stem

With these common types, the long ā stem appears in the third-person perfect forms: “he,” “she,” and “they.” First and second persons and “we” use a short-vowel stem before -ت، -نا، -توا.

Subject	قال-type	باع-type	نام-type
أنا / إنت	قُلْتْ ʾolt	بِعْتْ biʿt	نِمْتْ nimt
إنتي	قُلْتِي ʾolti	بِعْتِي biʿti	نِمْتِي nimti
هو	قَالْ ʾāl	بَاعْ bāʿ	نَامْ nām
هي	قَالِتْ ʾālit	بَاعِتْ bāʿit	نَامِتْ nāmit
إحنا	قُلْنَا ʾolna	بِعْنَا biʿna	نِمْنَا nimna
إنتوا	قُلْتُوا ʾoltu	بِعْتُوا biʿtu	نِمْتُوا nimtu
هما	قَالُوا ʾālu	بَاعُوا bāʿu	نَامُوا nāmu

This is a practical comparison, not a promise that every hollow verb has the same short vowel as the heading verb. شاف / شفت / بيشوف shāf / shuft / biyshūf “see” demonstrates lexical short-vowel variation even within the broader long-ū imperfect group.

Diagnostic 3: Egyptian aspect surrounds the alternating stem

The perfect presents a bounded event. The b-imperfect describes an ongoing or habitual situation, and context distinguishes those readings. Compare the same form بيقول in this time-context minimal pair:

هو بيقول رأيه دلوقتي

huwwa biyʾūl raʾyu dilwaʾti

He's giving his opinion now. (informal; ongoing)

هو بيقول رأيه في كل اجتماع

huwwa biyʾūl raʾyu fi kull igtimāʿ

He gives his opinion in every meeting. (informal; habitual)

A modal licenses the bare imperfect, while حـ marks an independent projection.

عايز أقولك حاجة قبل ما أمشي

ʿāyiz ʾaʾullak ḥāga ʾabl ma ʾamshi

I want to tell you something before I leave. (informal, to one man)

حبيع المكتب القديم الشهر الجاي

ḥa-bīʿ il-maktab il-ʾadīm ish-shahr il-gāy

I'll sell the old desk next month. (informal)

The hollow alternation is not an English tense. بـ, bare imperfect, حـ, participles, كان, and context retain their ordinary Egyptian functions.

Negation, clitics, and valency

The short perfect stem remains inside verbal ما...ش. Object and recipient clitics attach before -ش. Compare the required positive-to-negative pair:

قلته في الاجتماع

ʾoltu fil-igtimāʿ

I said it in the meeting. (neutral; positive)

ماقلتهوش في الاجتماع

maʾoltehūsh fil-igtimāʿ

I didn't say it in the meeting. (neutral; negative)

Valency remains lexical. قال can take an utterance, an إن clause, or a recipient with لـ. باع takes the item sold directly, often a buyer with لـ and a price with بـ. نام is intransitive: a pronoun belongs on a preposition in نمت عندهم, not as a direct-object suffix on the verb.

💡

Weak-stem alternation never overrides complement structure. First choose the correct lexical frame; then attach its pronoun to the verb or preposition that actually licenses it.

Two-turn Cairene dialogue

أ: قلت لسارة إنك حتبيع العربية؟

A: ʾolt li-Sāra innak ḥa-tibīʿ il-ʿarabiyya?

A: Did you tell Sara that you're going to sell the car? (informal, to one man)

ب: لأ، كانت نامت قبل ما أرجع

B: laʾ, kānit nāmit ʾabl ma ʾargaʿ

B: No; she had gone to sleep before I got back. (informal)

The question combines a short-stem perfect with future حـ. The answer uses كانت + perfect to locate sleeping before the return; a state-focused answer could instead use كانت نايمة “she was asleep.”

Register and variation

These hollow paradigms are core mainstream Cairene (informal/neutral). MSA shares the roots and traditional class label but has different prefix vowels, mood endings, and formal pronunciations. Ordinary Cairo pronounces ق in قال as /ʾ/; Upper Egyptian, Bedouin, some Delta or rural communities, learned speech, and performance language may use /g/ or /q/. The vowels of individual verbs can also vary regionally. Those alternatives must be labeled, not blended into the production baseline.

Common Mistakes

Keeping the long stem before every suffix

❌ أنا قالت له الحقيقة

Incorrect agreement and stem choice — first singular uses قلت.

✅ أنا قلتله الحقيقة

ʾana ʾoltillu il-ḥaʾīʾa

I told him the truth. (informal)

Copying قال's vowels onto نام

❌ أنا نومت بدري

Incorrect for ‘I slept’ — نومت is causative ‘I put someone to sleep.’

✅ أنا نمت بدري

ʾana nimt badri

I went to sleep early. (informal)

Omitting b- in an independent habit

❌ هو يقول رأيه كل يوم

Incorrect for the intended ordinary Cairene habit — the bare imperfect is unlicensed.

✅ هو بيقول رأيه كل يوم

huwwa biyʾūl raʾyu kull yōm

He gives his opinion every day. (informal)

Separating the object from verbal negation

❌ ما قلت هوش

Incorrect — the object clitic and -ش belong inside one verb word.

✅ ماقلتهوش

maʾoltehūsh

I didn't say it. (informal)

Adding an MSA reading

هو بيقول الحقيقة

huwwa biyʾūl il-ḥaʾīʾa

huwa yaqūlu al-ḥaqīqata

Pronunciation/register error — the MSA stem and endings do not belong to this Cairene sentence.

Key Takeaways

Hollow verbs alternate between long and short stems, but the vowels are lexical. Learn قال–قلت–بيقول, باع–بعت–بيبيع, and نام–نمت–بينام separately. Then apply ordinary Egyptian person marking, aspect prefixes, negation, clitic order, and complement frames around the correct stem.
