مدة الاسترجاع ورسوم الشحن في سياسة الاستبدال والاسترجاع.

It is most naturally understood as a phrase or heading, not a full sentence.

A full sentence usually has a clearer subject-predicate structure or a verb. Here, the text is simply naming a topic:

مدة الاسترجاع ورسوم الشحن في سياسة الاستبدال والاسترجاع

This is the kind of wording you might see as a section title on a website, such as:

• return period
• shipping fees
• in the exchange and return policy

So a learner should recognize that Arabic, especially in headings and menu items, often uses noun phrases without a verb.

مدة means period, duration, or length of time.

In this phrase, مدة الاسترجاع means the return period or the duration allowed for returns.

It is grammatically feminine because مدة is a feminine noun in Arabic. You can often tell from the ـة ending, though not every feminine noun has it, and not every noun with that shape behaves identically in every context.

Because it is feminine, if you later refer to it with an adjective, that adjective would also be feminine. For example:

• مدة طويلة = a long period

It appears twice because it plays two different roles:

1. In مدة الاسترجاع, it means the return process as the thing whose duration is being discussed.
2. In سياسة الاستبدال والاسترجاع, it is part of the compound phrase exchange and return policy.

So this repetition is completely natural. English can also repeat words in similar cases, even if style sometimes tries to avoid it.

Also, الاسترجاع is a verbal noun, often translated as returning or return depending on context.

These two words are related but not the same:

• الاسترجاع = return
• الاستبدال = exchange or replacement

So:

• سياسة الاستبدال والاسترجاع = exchange and return policy

This is a very common retail/business expression.

A useful way to think about them:

• استرجاع: the customer gives the item back
• استبدال: the customer swaps it for another item or a replacement

رسوم is the plural of رسم, and it means fees or charges.

Arabic often uses the plural in places where English might use either singular or plural depending on style. So:

• رسوم الشحن = shipping fees / shipping charges

Even if there is only one shipping cost in practice, Arabic commonly uses رسوم as a general category term.

This is similar to how English often says fees in formal or business language, even when referring to one kind of payment.

This is because of the iḍāfa structure, often called the construct phrase.

In مدة الاسترجاع:

• مدة = the first noun in the iḍāfa
• الاسترجاع = the second noun

In Arabic, the first noun in an iḍāfa usually does not take ال. Its definiteness is determined by the second noun.

So:

• مدة الاسترجاع = the return period
• not المدة الاسترجاع

The same thing happens in:

• رسوم الشحن = shipping fees
• سياسة الاستبدال والاسترجاع = exchange and return policy

This is one of the most important grammar patterns in Arabic.

Yes. A useful breakdown is:

• مدة الاسترجاع = the return period
• و = and
• رسوم الشحن = shipping fees
• في = in
• سياسة الاستبدال والاسترجاع = the exchange and return policy

So the structure is:

[noun phrase] + and + [noun phrase] + in + [noun phrase]

More specifically:

1. مدة الاسترجاع
   an iḍāfa phrase

2. رسوم الشحن
   another iḍāfa phrase

3. سياسة الاستبدال والاسترجاع
   another iḍāfa phrase, with coordination inside it

This sentence is a good example of how much Arabic relies on noun phrases.

في usually means in, within, or inside.

Here it links the topic to the document or section where that information is found:

• في سياسة الاستبدال والاسترجاع = in the exchange and return policy

So the whole phrase means something like:

• return period and shipping fees in the exchange and return policy

This use is very natural in Arabic when referring to information contained within a policy, document, page, or section.

It is best understood as an iḍāfa followed by coordination inside the second part.

Main structure:

• سياسة = policy
• الاستبدال والاسترجاع = exchange and return

So:

• سياسة الاستبدال والاسترجاع = policy of exchange and return

Inside the second part, الاستبدال and الاسترجاع are joined by و:

• الاستبدال والاسترجاع = exchange and return

So you can think of it as:

• one main iḍāfa: سياسة + [الاستبدال والاسترجاع]

A careful pronunciation in MSA would be approximately:

muddat al-istirjāʿ wa-rusūm ash-shaḥn fī siyāsat al-istibdāl wa-l-istirjāʿ

A few pronunciation notes:

• مدة is pronounced mudda or muddat depending on pause and context.
• In connected speech, the ـة often sounds like t before the next word in an iḍāfa, so مدة الاسترجاع becomes muddat al-istirjāʿ.
• الشحن begins with ش, and because ش is a sun letter, ال assimilates:
  • الشحن is pronounced ash-shaḥn, not al-shaḥn
• الاستبدال and الاسترجاع keep the l sound of al-, because ا is not a sun letter in this context:
  • al-istibdāl
  • al-istirjāʿ

Because ش is a sun letter.

When ال comes before a sun letter, the l sound is not pronounced, and the following consonant is doubled.

So:

• الشحن
• written with ال
• pronounced ash-shaḥn

This is a pronunciation rule, not a spelling change. The spelling stays the same.

Other examples:

• الشمس = ash-shams
• الرسوم = ar-rusūm

This is one of the key pronunciation rules learners need to master.

Because in normal everyday Arabic writing, especially in headings, websites, and modern printed text, short vowels and case endings are usually omitted.

So although a fully vowelled version could show endings, the unvowelled text is the normal real-world form.

That means learners usually have to infer grammar from structure rather than visible endings.

For example, this text is perfectly natural as written:

مدة الاسترجاع ورسوم الشحن في سياسة الاستبدال والاسترجاع

This is especially common in:

• headlines
• menu items
• app interfaces
• policy pages
• advertisements

Yes. Even if the meaning is already known, it is useful to notice that Arabic noun phrases often allow several smooth English renderings.

Possible translations include:

• Return period and shipping fees in the exchange and return policy
• Return timeframe and shipping charges in the exchange and return policy
• The return period and shipping fees under the exchange and return policy
• Return period and shipping costs in the returns and exchanges policy

The exact English wording depends on style, but the Arabic structure remains the same.

Both are examples of verbal nouns built from Form X verbs, a pattern learners often meet in formal MSA.

• استرجاع comes from a root related to returning or recovering
• استبدال comes from a root related to changing or substituting

The beginning استـ is a very common pattern in derived forms.

For learners, the most important practical point is this:

• words that look like استفعال-type nouns are often abstract action nouns used in formal writing
• in English, they are often translated as return, replacement, exchange, use, recovery, and so on depending on context

You do not need to master all the morphology at once, but recognizing that these are formal action nouns will help a lot when reading business or administrative Arabic.
