تستمر ورشة الفخار طوال الصباح.

This is a very common Arabic word order: verb + subject + other information.

So:

تستمر ورشة الفخار طوال الصباح = continues the pottery workshop throughout the morning

In natural English, we usually reorder it as:

The pottery workshop continues throughout the morning.

Arabic can also use subject + verb order, but starting with the verb is very normal in MSA.

Because the subject ورشة is a feminine singular noun.

• ورشة = workshop
• It is grammatically feminine
• So the verb must also be feminine singular in the present tense

That is why we get:

• تستمر = it continues for a feminine subject

If the subject were a masculine noun, you would expect a different form, such as يستمر.

Yes. تستمر is the present/imperfect form of the verb استمرّ, meaning to continue or to last.

Depending on context, the Arabic present tense can mean things like:

• continues
• is continuing
• continues to run
• sometimes even a future sense, if the context supports it

In this sentence, the most natural meaning is something like:

The pottery workshop continues / lasts throughout the morning.

Because ورشة الفخار is an iḍāfa construction, often called a genitive construct or noun-noun construction.

In an iḍāfa:

• the first noun usually does not take الـ
• the second noun determines whether the whole phrase is definite or indefinite

So:

• ورشةُ الفخارِ = the pottery workshop
• ورشةُ فخارٍ = a pottery workshop

Here, الفخار is definite, so the whole phrase ورشة الفخار is definite.

It is an iḍāfa phrase:

• ورشة = workshop
• الفخار = pottery

Together:

ورشة الفخار = the pottery workshop
literally, workshop of the pottery / pottery workshop

Important things to notice:

1. The first noun (ورشة) does not take الـ
2. The second noun (الفخار) is in the genitive
3. The whole phrase acts like one unit

This structure is extremely common in Arabic.

Because ورشة ends in ة (tāʾ marbūṭa).

When a word with tāʾ marbūṭa is said by itself in pause, it usually sounds like -a:

• ورشة = warsha

But when it is followed by another word in grammar-connected speech, especially in an iḍāfa, the ة is pronounced as t:

• ورشةُ الفخارِ = warshatu l-fikhāri or warshat al-fikhār in connected reading

So learners often hear both:

• isolated: warsha
• in this phrase: warshat al-fikhār

الفخار means pottery or ceramics, depending on context.

So ورشة الفخار is a workshop related to pottery, such as:

• a pottery workshop
• a ceramics workshop

In this sentence, it describes the type of workshop.

طوال means throughout, for the whole of, or all through.

So:

• طوال الصباح = throughout the morning / all morning long

Arabic often uses طوال directly with a time expression, without needing a separate preposition like English throughout sometimes does.

It functions as a time expression on its own here.

Because طوال is followed by the span of time it covers.

So:

• طوال الصباح = throughout the morning
• literally something like the whole length of the morning

Grammatically, طوال is treated as the first part of a construction, and الصباح comes after it as the second part.

Yes. In fully vocalized MSA, the sentence would be read approximately as:

تَسْتَمِرُّ وَرْشَةُ الْفِخَارِ طَوَالَ الصَّبَاحِ

The case/mood endings are:

• تستمرُّ: final -u because it is a present-tense indicative verb
• ورشةُ: -u because it is the subject
• الفخارِ: -i because it is the second noun in an iḍāfa
• طوالَ: -a as an adverbial/time expression
• الصباحِ: -i because it follows طوال in this construction

In normal unvocalized writing, these short vowels are usually omitted.

Yes, absolutely.

Depending on context, natural English translations include:

• The pottery workshop continues throughout the morning.
• The pottery workshop lasts all morning.
• The pottery workshop goes on throughout the morning.

All of these capture the basic idea of تستمر ... طوال الصباح.

Yes. Some possible alternatives are:

• طوال الصباح = throughout the morning
• طيلة الصباح = throughout the morning / all morning
• خلال الصباح = during the morning

These are similar, but not always identical in nuance:

• طوال and طيلة emphasize the full duration
• خلال often means simply during

So تستمر ورشة الفخار طوال الصباح strongly suggests the workshop runs for the whole morning.
