تقرير الحادث جاهز اليوم.

Because Arabic often uses a nominal sentence in the present tense, with no written or spoken verb meaning "is".

So:

• تقرير الحادث = the accident report
• جاهز = ready
• اليوم = today

Together, the sentence means The accident report is ready today.

If you wanted to say was or will be, Arabic would usually add a verb, such as:

• كان تقرير الحادث جاهزًا = The accident report was ready
• سيكون تقرير الحادث جاهزًا = The accident report will be ready

This is an iḍāfa construction, often called a genitive/possessive phrase.

It literally works like:

• تقرير = report
• الحادث = the accident

So تقرير الحادث means:

• the accident report
• literally, report of the accident

In an iḍāfa:

1. the first noun (تقرير) does not take ال
2. the second noun (الحادث) can be definite or indefinite
3. the whole phrase gets its definiteness from the second noun

Since الحادث is definite (the accident), تقرير الحادث means the accident report, not just an accident report.

Because in an iḍāfa, the first noun normally does not take الـ.

So Arabic says:

• تقرير الحادث = the accident report

not:

• التقرير الحادث ❌

The definiteness comes from the whole phrase. Since the second word is definite, the whole phrase is definite.

A useful comparison:

• كتابُ طالبٍ = a student’s book / a book of a student
• كتابُ الطالبِ = the student’s book

Likewise:

• تقريرُ حادثٍ = a report of an accident
• تقريرُ الحادثِ = the report of the accident / the accident report

جاهز is the predicate of the sentence, describing the subject تقرير الحادث.

So the structure is:

• تقرير الحادث = subject/topic
• جاهز = predicate/comment
• اليوم = time expression

In English, we often need is:

• The accident report is ready today

In Arabic, جاهز can stand directly as the predicate in the present tense.

Also, جاهز is an adjective meaning ready, but in this kind of sentence it functions like is ready.

Because it agrees with تقرير, which is a masculine singular noun.

• تقرير = masculine singular
• so the predicate is جاهز

If the subject were feminine singular, you would usually use جاهزة:

• الوثيقة جاهزة = The document is ready

If it were masculine plural, the form would change accordingly:

• التقارير جاهزة = The reports are ready

So here, جاهز matches تقرير.

Here اليوم means today, and it tells you when the report is ready.

So the sentence means:

• The accident report is ready today

It does not mean today’s accident report.

If you wanted today’s report, you would need a different structure, such as something like:

• تقرير اليوم = today’s report

But in تقرير الحادث جاهز اليوم, اليوم modifies the whole statement, not the noun تقرير by itself.

Yes, Arabic word order is somewhat flexible.

The most neutral order here is:

• تقرير الحادث جاهز اليوم

But you could also say:

• تقرير الحادث اليوم جاهز
• اليوم تقرير الحادث جاهز

These can sound slightly different in emphasis:

• putting اليوم first can emphasize today
• keeping جاهز right after the subject is often the clearest basic pattern

For a learner, تقرير الحادث جاهز اليوم is a very good standard version.

A fully vowelled version would usually be:

تَقْريرُ الحادِثِ جاهِزٌ اليَوْمَ

These endings reflect classical/fully inflected grammar:

• تقريرُ: nominative, because it is the subject of the nominal sentence
• الحادثِ: genitive, because it is the second term of the iḍāfa
• جاهزٌ: nominative, because it is the predicate
• اليومَ: accusative as an adverbial expression of time

In normal modern writing, these short vowel endings are usually omitted:

• تقرير الحادث جاهز اليوم

A careful pronunciation would be approximately:

taqrīru l-ḥādithi jāhizun al-yawma

In pause, or in everyday reading without case endings, you will often hear something closer to:

taqrīr al-ḥādith jāhiz il-yawm

A simpler learner-friendly transliteration is:

taqriir al-haadith jaahiz al-yawm

A few pronunciation notes:

• ق in تقرير is a deep q sound, not exactly like English k
• ح in حادث is a stronger breathy h
• ج in MSA is usually like j in judge

Sometimes yes, depending on context.

The noun حادث can refer to an accident, event, or incident, but in many everyday contexts it is understood as accident.

So:

• تقرير الحادث often means the accident report
• in another context, it could be the incident report

The correct English choice depends on the situation. If this sentence appears in a police, insurance, or workplace context, accident report is a very natural translation.

Yes. It is completely natural in Modern Standard Arabic.

It is short, clear, and typical of formal written Arabic such as:

• official notices
• workplace communication
• news-style writing
• administrative language

A native speaker might also use similar wording in speech, especially in formal contexts. In everyday dialect conversation, the exact wording might change, but the MSA sentence itself is perfectly correct and natural.
