كل من شارة الاسم وبرنامج المؤتمر عند مكتب التسجيل.

Here كل من ... و... means both ... and ....

So:

• كل من شارة الاسم وبرنامج المؤتمر = both the name badge and the conference program

Literally, كل often means all/every, and من often means of/from, but together in this pattern it works idiomatically to link two items.

A good way to remember it is:

• كل من X وY = both X and Y

Because in Arabic, in a present-tense nominal sentence, the verb to be is usually omitted.

So Arabic says:

• شارة الاسم ... عند مكتب التسجيل
• literally: the name badge ... at the registration desk

But in natural English, you translate it as:

• The name badge is at the registration desk

The full sentence therefore means:

• Both the name badge and the conference program are at the registration desk

This is completely normal in Arabic.

عند usually means at, by, or sometimes with depending on context.

So:

• عند مكتب التسجيل = at the registration desk

Word by word:

• عند = at / by
• مكتب = desk / office
• التسجيل = registration

So مكتب التسجيل is the registration desk or the registration office, depending on context.

This is a very natural question.

• في usually means in or inside
• عند often means at or by

A registration desk is not really something you are inside, so عند is more natural here.

Compare:

• في الغرفة = in the room
• عند الباب = at the door
• عند مكتب التسجيل = at the registration desk

So عند gives the sense of location near or at that place.

شارة الاسم is an iḍāfa construction, often called a genitive construction or noun-noun construction.

It literally means:

• شارة = badge
• الاسم = the name

Together:

• شارة الاسم = the badge of the name
• natural English: name badge

Important things about iḍāfa:

1. The first noun usually does not take الـ.
2. The second noun can make the whole phrase definite.

So:

• شارة اسم = a name badge / badge of a name
• شارة الاسم = the name badge / name badge

In English we often reverse the order when translating.

Yes. برنامج المؤتمر is also an iḍāfa construction.

Word by word:

• برنامج = program
• المؤتمر = the conference

Together:

• برنامج المؤتمر = the program of the conference
• natural English: the conference program

So both noun phrases in the sentence are built the same way:

• شارة الاسم = name badge
• برنامج المؤتمر = conference program

Because و means and.

The pattern is:

• كل من X وY

So you need the و before the second item:

• كل من شارة الاسم وبرنامج المؤتمر

This is the normal way to say:

• both the name badge and the conference program

Without the و, the sentence would not sound right in this structure.

The sentence is a nominal sentence:

• كل من شارة الاسم وبرنامج المؤتمر = the topic / subject
• عند مكتب التسجيل = the predicate, telling where they are

So the structure is basically:

• [Both items] + [at the registration desk]

Arabic often uses this kind of structure for simple statements about location.

One possible full reading is:

كُلٌّ مِن شَارَةِ الاسْمِ وَبَرْنَامَجِ الْمُؤْتَمَرِ عِنْدَ مَكْتَبِ التَّسْجِيلِ

A simple pronunciation guide:

• kullun min
• shaarat al-ism
• wa barnaamaj al-mu’tamar
• ʿinda maktab at-tasjeel

In normal Arabic writing, these short vowels are usually omitted, so learners are expected to recognize the words from context.

Not in natural English. Even though كل can be related to the idea of each/every, this whole pattern كل من X وY is best understood as:

• both X and Y

So for this sentence, the most natural translation is:

• Both the name badge and the conference program are at the registration desk.

That is how an English speaker should usually understand it.
