مش المفروض ادفع رسوم الشحن تاني.

مش المفروض is a very common Egyptian expression meaning something like:

• I’m not supposed to...
• I shouldn’t be expected to...
• I shouldn’t have to...

In this sentence, it gives a sense of expectation or what is considered correct/fair, not just simple ability.

So مش المفروض ادفع رسوم الشحن تاني is stronger than just I’m not paying again. It suggests: I should not be expected to pay the shipping fees again.

Because the verb itself already shows the subject.

ادفع means I pay / I should pay / I am to pay, depending on context. The أ- at the beginning marks first person singular.

So:

• ادفع = I pay
• أنا ادفع = I pay too, but with an explicit pronoun

In Egyptian Arabic, subject pronouns are often omitted unless you want emphasis or contrast.

After expressions like المفروض, Arabic normally uses the imperfect/present-form verb.

So the structure is:

• المفروض + imperfect verb
• مش المفروض + imperfect verb

Literally, it is something like it is supposed that I pay, but in natural English we translate it as I’m supposed to pay or I should pay.

That is why Arabic uses ادفع rather than an infinitive like English to pay. Arabic does not use an infinitive here the way English does.

رسوم الشحن means shipping fees or shipping charges.

About رسوم:

• It is the plural of رسم in the sense of a fee/charge
• Arabic often uses a plural noun for kinds of fees or charges even when English might sometimes say the shipping fee in the singular

So even if one single charge is being discussed, رسوم الشحن can still sound natural as shipping charges/fees.

تاني means again or a second time.

So:

• ادفع رسوم الشحن تاني = pay the shipping fees again

In Egyptian Arabic, تاني often comes at the end of the sentence or phrase. That placement is very common and natural.

In Egyptian Arabic, adverbs like تاني are often placed toward the end of the sentence.

So:

• ادفع رسوم الشحن تاني = very natural
• moving تاني earlier is possible in some contexts, but the end position is the most straightforward and common here

English learners sometimes expect again to be placed more flexibly, but Arabic often has its own preferred rhythm and placement.

A natural pronunciation would be:

mish el-mafrood adfaʿ rusoom ish-shaḥn tani

A few notes:

• مش = mish
• المفروض = el-mafrood
• ادفع = adfaʿ
• رسوم = rusoom
• الشحن is pronounced with the sh sound doubled because ش is a sun letter, so الـ assimilates:
  • الشحن → ish-shaḥn / esh-shaḥn
• تاني = tani

You may also hear slight vowel differences depending on speaker and region.

It is understandable and natural enough, but it sounds a bit more formal or business-like.

In everyday Egyptian speech, many people might also say:

• مصاريف الشحن = shipping costs / shipping charges

So both are possible, but:

• رسوم الشحن feels a bit more formal or written
• مصاريف الشحن feels a bit more everyday-colloquial

The rest of the sentence, especially مش المفروض and تاني, is clearly colloquial Egyptian.

Yes. That is one of the important nuances of مش المفروض.

Depending on context, it can mean:

• I’m not supposed to pay the shipping fees again
• I shouldn’t have to pay the shipping fees again
• It isn’t expected that I pay the shipping fees again

In real usage, it often carries a mild complaint or protest, so I shouldn’t have to pay again is often a very natural English rendering.

Yes, absolutely.

Adding إني makes the clause more explicit:

• مش المفروض ادفع رسوم الشحن تاني
• مش المفروض إني ادفع رسوم الشحن تاني

Both are possible.

The version without إني is very common and a little more direct and compact.
The version with إني can sound slightly fuller or more explicit, but it does not change the core meaning much.

They are close, but not identical.

• مش المفروض = I’m not supposed to / I shouldn’t be expected to
• مش لازم = I don’t have to / it isn’t necessary

So:

• مش المفروض ادفع رسوم الشحن تاني suggests that paying again would be unfair, unexpected, or contrary to what should happen
• مش لازم ادفع رسوم الشحن تاني simply says it is not necessary for me to pay again

In many situations, مش المفروض has a stronger tone of complaint or principle.
