تقدير الأضرار من ورشة الإصلاح.

Not really. In normal grammar, this is best understood as a noun phrase, not a complete verbal sentence.

A natural English equivalent is something like:

• damage estimate from the repair shop
• an estimate of the damage from the repair shop

So this kind of phrase is very common as:

• a title
• a heading
• a label on a form or document

If you wanted a full sentence, you might say something like:

• هذا تقديرُ الأضرارِ من ورشةِ الإصلاحِ = This is the damage estimate from the repair shop.

Here تقدير means estimate.

The root is ق د ر, which is connected with ideas like:

• measuring
• determining
• estimating

So تقدير الأضرار means:

• estimate of the damages
• more naturally in English: damage estimate

Be aware that تقدير can mean different things in other contexts, such as:

• appreciation
• evaluation
• assessment

But in this phrase, estimate is the right meaning.

Because this is an iḍāfa construction, often called a construct phrase.

In Arabic, when two nouns are linked as X of Y, the structure is:

• first noun: no ال
• second noun: often definite if the whole phrase is definite

So:

• تقدير الأضرار = estimate of the damages

Here:

• تقدير = the first noun in the iḍāfa
• الأضرار = the second noun

The first noun in an iḍāfa normally does not take ال.

So التقدير الأضرار would be wrong for this meaning.

Because it refers to the damage/the damages being estimated.

In the iḍāfa تقدير الأضرار:

• تقدير = estimate
• الأضرار = the damage(s)

When the second noun is definite, the whole iḍāfa becomes definite in meaning.

So:

• تقدير أضرار = an estimate of damages
• تقدير الأضرار = the estimate of the damages or more naturally the damage estimate

This is one of the key features of iḍāfa: the definiteness is determined by the second noun.

Yes, that is a very common point of confusion.

In Arabic, ضرر means harm or damage, and أضرار is the plural, often used where English might still prefer singular damage.

So:

• الأضرار literally = the damages
• but idiomatic English often says simply the damage

This is a translation difference, not a grammar problem.

Arabic often uses أضرار in practical contexts like:

• insurance
• accidents
• repairs
• legal or technical reports

So تقدير الأضرار is a very normal expression for damage estimate.

Here من most naturally means from:

• تقدير الأضرار من ورشة الإصلاح
• damage estimate from the repair shop

That is, the estimate comes from the repair shop.

Depending on context, English might also express this as:

• by the repair shop
• issued by the repair shop

But the Arabic preposition used is من, whose basic meaning is from.

So the phrase suggests the source of the estimate.

This is another iḍāfa construction:

• ورشة = workshop / shop
• الإصلاح = repair

So:

• ورشة الإصلاح = the repair shop
• literally: the workshop of repair

This is a normal Arabic way to form compound nouns.

You can think of it as:

• ورشةُ الإصلاحِ
• first noun: ورشة
• second noun: الإصلاح

Since الإصلاح is definite, the whole phrase is definite: the repair shop.

Because Arabic and English handle definiteness differently in this structure.

In Arabic iḍāfa:

• the first noun usually has no ال
• the second noun determines whether the whole phrase is definite

So:

• تقدير الأضرار is already definite in meaning because الأضرار is definite

Even though تقدير has no ال, the whole phrase can still mean:

• the damage estimate

This is very normal in Arabic.

A careful reading is:

taqdīr al-aḍrār min warshat al-iṣlāḥ

A few pronunciation notes:

• تقدير = taq-dīr
• الأضرار = al-aḍ-rār
• ورشة = war-sha
• الإصلاح = al-iṣ-lāḥ

If someone reads full case endings in very formal Arabic, it would be:

taqdīru l-aḍrāri min warshati l-iṣlāḥi

But in normal reading, especially outside very formal recitation, learners usually hear something closer to:

taqdīr al-aḍrār min warshat al-iṣlāḥ

In everyday written Arabic, short vowel case endings are usually not written.

So the phrase appears as:

• تقدير الأضرار من ورشة الإصلاح

But in fully vocalized, formal grammar terms, it could be analyzed with endings such as:

• تقديرُ الأضرارِ من ورشةِ الإصلاحِ

if it stands as a subject or title-like nominative phrase

or possibly another case depending on the larger sentence it appears in.

For most learners at an early or intermediate stage, the important point is:

• the written form usually leaves these endings out
• native readers understand them from context

Yes. That is possible.

Depending on context, تقدير can be translated as:

• estimate
• assessment
• evaluation

In practical contexts such as:

• car repair
• insurance claims
• accident reports

the most natural English translation is often:

• damage estimate from the repair shop

But assessment of damages from the repair shop is not wrong; it is just a bit less natural in many everyday situations.

Yes, there can be a small ambiguity if the context is missing.

The phrase most likely means:

• the repair shop’s damage estimate
• a damage estimate from the repair shop

But without context, someone could briefly wonder whether من ورشة الإصلاح is describing:

• the source of the estimate, or
• the source/cause of the damage

In real life, context usually makes it clear that it means the estimate is from the repair shop, not that the damage came from the repair shop.

If you wanted to make the source idea even clearer, Arabic context or a fuller sentence would usually do that.
