العصير بدون سكر.

Because الـ is the Arabic definite article, equivalent to the in English.

• عصير = juice
• العصير = the juice

In short menu-style phrases like this, Arabic often uses the definite form where English might or might not. So العصير بدون سكر can be understood as the juice without sugar or simply juice without sugar, depending on context.

بدون means without.

It is very common in Modern Standard Arabic and everyday usage. In this sentence:

• العصير = the juice
• بدون = without
• سكر = sugar

So the structure is literally the juice without sugar.

You may also see related expressions such as من دون or بلا, which can also mean without, but بدون is very common and straightforward for learners.

Because Arabic often allows verbless sentences, especially in the present tense.

In English, you usually need a verb like is:

• The juice is without sugar
• or more naturally, The juice is unsweetened / without sugar

In Arabic, the present-tense is is often omitted. So:

• العصير بدون سكر literally looks like the juice without sugar
• but it functions like The juice is without sugar

This is completely normal in Arabic.

Here سكر means sugar in a general, uncountable sense, so it is left indefinite.

• سكر = sugar
• السكر = the sugar

In the phrase without sugar, English also uses sugar without the, and Arabic does the same:

• بدون سكر = without sugar

If you said بدون السكر, it would sound more like without the sugar, referring to some specific sugar already known from context.

A simple pronunciation guide is:

al-ʿa-seer bi-doon suk-kar

A few notes:

• العصير = al-ʿaṣīr
  • the ع sound is a deep Arabic consonant with no exact English equivalent
  • ص is an emphatic s
• بدون = bi-dūn
• سكر = sukkar
  • the k is doubled in pronunciation because of the doubled consonant

A more careful transliteration would be:

al-ʿaṣīr bidūn sukkar

It is usually written as one word: بدون.

Historically, it is related to بـ + دون, but in normal modern writing you will commonly see it as a single word.

You may also encounter:

• من دون = without
• بلا = without

All are possible, but بدون is very common and easy to recognize.

The order is:

noun + prepositional phrase

So:

• العصير = the juice
• بدون سكر = without sugar

Together:

• العصير بدون سكر

This is very natural in Arabic. The phrase بدون سكر describes the juice.

It can function as either, depending on context.

1. As a phrase
   It can mean something like:

   • juice without sugar
   • the juice without sugar

2. As a complete verbless sentence
   In context, it can mean:

   • The juice is without sugar

This kind of short expression is especially common on menus, labels, signs, and in simple conversation.

In fully formal Classical/Modern Standard Arabic with full case endings, it could be read approximately as:

العَصيرُ بِدونِ سُكَّرٍ

That reflects grammatical case in very careful reading.

However, in normal speech and in most unvowelled writing, learners will usually hear or say:

العصير بدون سكر

without clearly pronouncing the endings.

So yes, case endings exist in formal grammar, but they are often not pronounced in everyday use.

Yes. Both are possible.

• العصير بدون سكر = the juice without sugar
• العصير بلا سكر = the juice without sugar
• العصير من دون سكر = the juice without sugar

The meaning is very similar. For a learner:

• بدون is very common and practical
• بلا is shorter and also common in formal Arabic
• من دون is slightly more explicit in structure

All three are useful to recognize.

Yes—سكر is a very common word and usually means sugar.

A useful point for learners: Arabic often uses singular mass nouns where English also uses a mass noun, so سكر works naturally for sugar in general.

Also, be aware that Arabic roots can produce related words. From the same consonants you may meet words connected to sweetness or sugar in different contexts, but in this sentence سكر simply means sugar.
