Arabic often expresses what English packages into one adverb with a preposition plus a noun. بسرعة means “quickly,” من جديد means “again/anew,” and على الفور means “immediately.” Each complete phrase functions adverbially, but its noun is genitive because a preposition governs it. Calling the whole phrase an “adverb” therefore does not make its internal case accusative.
These phrases are normal in contemporary MSA across reporting, instructions, correspondence, and careful cross-regional speech. The general adverbial-accusative page contrasts them with bare or accusative forms; this page concentrates on their formation, placement, and scope.
One function, three different forms
Compare three ways to add information to an event:
| Form | Example | Internal grammar |
|---|---|---|
| lexicalized word | غدًا | conventional accusative time expression |
| accusative noun phrase | ساعةً كاملةً | noun and adjective are accusative |
| prepositional phrase | بسرعةٍ كبيرةٍ | noun and adjective are genitive after بـ |
The whole phrase بسرعة كبيرة answers “how?”, but سرعةٍ is genitive after بـ, and كبيرةٍ agrees with it. English “adverbial” describes the phrase's job in the larger clause; it does not name the case of every word inside it.
أرسل الممرض النتائج بسرعة إلى الطبيبة المناوبة.
ʾarsala l-mumarriḍu n-natāʾija bi-surʿatin ʾilā ṭ-ṭabībati l-munāwiba(h).
The nurse quickly sent the results to the doctor on duty.
أرسل الممرض النتائج إلى الطبيبة المناوبة على الفور.
ʾarsala l-mumarriḍu n-natāʾija ʾilā ṭ-ṭabībati l-munāwibati ʿalā l-fawr.
The nurse sent the results to the doctor on duty immediately.
In على الفور, the definite noun الفورِ is genitive after على. The phrase is a fixed, neutral-to-formal way to indicate that no delay intervenes.
بسرعة: manner without an English-style -ly form
The preposition بـ frequently combines with an abstract noun to express manner: بدقة “accurately,” بعناية “carefully,” بهدوء “calmly,” and بوضوح “clearly.” This is productive as a phrase pattern, but the noun still needs to be idiomatic. Not every English adjective has a natural Arabic بـ + noun translation.
قرأ المحرر الأرقام ببطء ودقة قبل النشر.
qaraʾa l-muḥarriru l-ʾarqāma bi-buṭʾin wa-diqqatin qabla n-nashr.
The editor read the figures slowly and accurately before publication.
راجعت المحاسبة الفاتورة بعناية شديدة.
rājaʿati l-muḥāsibatu l-fātūrata bi-ʿināyatin shadīda(h).
The accountant checked the invoice with great care.
The adjective شديدةٍ is feminine singular and genitive because it modifies عنايةٍ. It does not agree with the feminine subject المحاسبة by coincidence; both nouns happen to be feminine. Replace the subject with المحاسب and the phrase remains بعناية شديدة.
An adjective can instead describe a noun or participant:
كانت المراجعة سريعة، لكنها لم تكن سطحية.
kānati l-murājaʿatu sarīʿatan, lakinnahā lam takun saṭḥiyya(h).
The review was quick, but it was not superficial. (سريعة is an adjective.)
أجرت اللجنة المراجعة بسرعة من دون إهمال التفاصيل.
ʾajrati l-lajnatu l-murājaʿata bi-surʿatin min dūni ʾihmāli t-tafāṣīl.
The committee carried out the review quickly without neglecting the details. (بسرعة modifies the event.)
English uses related forms quick and quickly. Arabic changes the construction: adjectival سريع agrees with a noun, while adverbial بسرعة is a prepositional phrase.
من جديد: repeating with a fresh start
من جديد literally contains من plus genitive جديدٍ, but as a conventional phrase it means “again,” often with the nuance “anew” or “from the beginning.” It commonly follows the verb or object it modifies.
فتحنا الملف من جديد بعد اكتشاف الخطأ.
fataḥnā l-milaffa min jadīdin baʿda ktishāfi l-khaṭaʾ.
We reopened the file after discovering the error.
من جديد بدأ الفريق جمع البيانات، ولكن بطريقة مختلفة.
min jadīdin badaʾa l-farīqu jamʿa l-bayānāti, wa-lākin bi-ṭarīqatin mukhtalifa(h).
The team began collecting the data anew, but in a different way. (Marked initial reset.)
The second order is possible when a writer deliberately announces a reset. For a neutral statement, بدأ الفريق ... من جديد is smoother. The initial phrase is not a subject and does not affect verb agreement.
Do not assume من جديد and مرة أخرى are always interchangeable. Both can mean “again,” but مرة أخرى simply counts another occurrence more readily, whereas من جديد often evokes renewal or restarting.
طلب العميل نسخة أخرى، فطبعت العقد مرة أخرى.
ṭalaba l-ʿamīlu nuskhatan ʾukhrā, fa-ṭabaʿtu l-ʿaqda marratan ʾukhrā.
The client requested another copy, so I printed the contract again.
على الفور and the placement of urgency
على الفور is especially common in instructions, news, policies, and professional requests (formal/neutral). It normally follows the event, but it can be fronted when immediacy itself is the organizing point.
على الفور اتصلت الإدارة بخدمة الطوارئ.
ʿalā l-fawri ttaṣalati l-ʾidāratu bi-khidmati ṭ-ṭawāriʾ.
Immediately, the administration contacted the emergency service. (Immediacy is foregrounded.)
اتصلت الإدارة بخدمة الطوارئ على الفور عند ظهور الدخان.
ittaṣalati l-ʾidāratu bi-khidmati ṭ-ṭawāriʾi ʿalā l-fawri ʿinda ẓuhūri d-dukhān.
The administration contacted the emergency service immediately when smoke appeared.
Initial placement is stronger and works well in a sequence of urgent instructions. Final or postverbal placement is the ordinary unmarked choice. فورًا is a common lexicalized accusative with the same basic meaning; حالًا is also frequent, though it may feel more conversational in some contexts. There is no need to force one phrase into every register.
Habit and frequency can coexist with a prepositional adverbial
A frequency expression answers “how often?”, while a manner phrase answers “how?”. Their forms and positions remain independent.
عادة نجيب عن الرسائل بسرعة خلال ساعات العمل.
ʿādatan nujību ʿani r-rasāʾili bi-surʿatin khilāla sāʿāti l-ʿamal.
We usually answer messages quickly during working hours.
Here عادةً frames the habitual claim; بسرعةٍ gives the manner; خلالَ ساعاتِ العمل gives its time range. Several adverbials can coexist when each has a clear contribution.
Scope: adjacency prevents the wrong reading
Prepositional phrases can modify a verb, a noun, or the whole clause. Position helps the reader identify the intended attachment. Focus particles make adjacency especially important.
تحدثت إلى المديرة فقط بعد الاجتماع.
taḥaddathtu ʾilā l-mudīrati faqaṭ baʿda l-ijtimāʿ.
I spoke only to the director after the meeting. (فقط restricts the person.)
تحدثت إلى المديرة بعد الاجتماع فقط.
taḥaddathtu ʾilā l-mudīrati baʿda l-ijtimāʿi faqaṭ.
I spoke to the director only after the meeting. (فقط restricts the time.)
The preposition itself does not carry the scope contrast. The location of فقط does. In polished prose, do not rely on a hoped-for intonation when an adjacent placement can make the restriction explicit. See Preposition Scope for attachment beyond adverbial phrases.
Common Mistakes
Copying English -ly by changing an adjective ending
❌ كتب الطالب الإجابة دقيقا.
Incorrect for ‘The student wrote the answer accurately’—دقيقا is not a freely formed Arabic adverb.
✅ كتب الطالب الإجابة بدقة قبل تسليم الورقة.
kataba ṭ-ṭālibu l-ʾijābata bi-diqqatin qabla taslīmi l-waraqa(h).
The student wrote the answer accurately before handing in the paper.
Making a manner phrase agree with the performer
❌ قرأت الباحثة الوثائق سريعة.
Incorrect for ‘The researcher read the documents quickly’—subject agreement does not produce a manner adverb.
✅ قرأت الباحثة الوثائق بسرعة في الأرشيف.
qaraʾati l-bāḥithatu l-wathāʾiqa bi-surʿatin fī l-ʾarshīf.
The researcher read the documents quickly in the archive.
Giving the noun accusative case after a preposition
❌ بدقة شديدة في الاجتماع.
bi-diqqatan shadīdatan fī l-ijtimāʿ
Incorrect case reading—after بـ, read bi-diqqatin shadīdatin before the following phrase, not accusative bi-diqqatan shadīdatan.
✅ تعامل الموظف مع المشكلة بدقة شديدة في الاجتماع.
taʿāmala l-muwaẓẓafu maʿa l-mushkilati bi-diqqatin shadīdatin fī l-ijtimāʿ.
The employee handled the problem with great precision in the meeting.
Placing فقط beside the unintended constituent
❌ أرسلت النسخة إلى المراجع فقط صباح الأحد.
Wrong for the intended ‘I sent the copy only on Sunday morning’—this placement restricts the recipient, not the time.
✅ أرسلت النسخة إلى المراجع صباح الأحد فقط.
ʾarsaltu n-nuskhata ʾilā l-murājiʿi ṣabāḥa l-ʾaḥadi faqaṭ.
I sent the copy to the reviewer only on Sunday morning.
Key Takeaways
- A prepositional phrase can function adverbially while its noun remains genitive.
- بـ + abstract noun is a common manner pattern; it is not mechanical English-to-Arabic suffix replacement.
- من جديد often suggests restarting anew, while مرة أخرى readily counts another occurrence.
- على الفور is neutral-to-formal and may follow the event or be fronted to foreground urgency.
- Position shows attachment and scope; keep فقط beside the phrase it restricts.
