عندي سعال، صداع، دوار. ضغط الدم ودرجة الحرارة على الشاشة.

Arabic usually does not use a normal verb equivalent to English to have in sentences like this.

• عندي literally means at me or with me
• So عندي سعال is literally something like A cough is with me / at me
• In natural English, we translate it as I have a cough

This is a very common Arabic pattern:

• عندي صداع = I have a headache
• عنده حرارة = He has a fever
• عندها سؤال = She has a question

So the learner should think of عند + pronoun as one of the main ways Arabic expresses possession or a current condition.

The -ي is the attached pronoun meaning me / my.

Here is the breakdown:

• عند = at, by, with
• ي = me

So:

• عندي = with me / I have
• Pronounced roughly ʿindī

Other forms work the same way:

• عندك = you have
• عنده = he has
• عندها = she has
• عندنا = we have

This is an important pattern to memorize because it appears everywhere in Arabic.

They are indefinite nouns here, so they appear without الـ.

That means the speaker is saying:

• a cough
• a headache
• dizziness

rather than something like:

• the cough
• the headache
• the dizziness

In medical-style statements, Arabic often lists symptoms this way:

• عندي سعال
• عندي صداع
• عندي دوار

or in shorter note-like style:

• عندي سعال، صداع، دوار

So the lack of الـ is normal and natural.

In full, careful prose, Arabic often does use و before the last item, just as English often uses and:

• سعال وصداع ودوار
• or سعال، صداع، ودوار

But in short notes, medical forms, captions, and clipped speech, Arabic often omits repeated conjunctions and simply lists items with commas.

So this version feels concise and practical, almost like a symptom checklist:

• سعال، صداع، دوار

That is not strange here; it matches the brief style of the sentence.

Here they are nouns.

• سعال = cough
• صداع = headache
• دوار = dizziness / vertigo

They are being listed as symptoms, so Arabic treats them as things someone has.

That is why the structure is:

• عندي سعال
• not something like أنا سعال

A learner may notice that some of these words can behave a little differently in other contexts, but in this sentence they are straightforward symptom nouns.

This is a very common feature of Arabic: in the present tense, Arabic often leaves out the verb to be.

So:

• ضغط الدم ودرجة الحرارة على الشاشة

literally looks like:

• blood pressure and temperature on the screen

but it means:

• Blood pressure and temperature are on the screen

This is called a nominal sentence. Arabic does this all the time in the present tense:

• الكتاب على الطاولة = The book is on the table
• أنا بخير = I am fine
• الجو جميل = The weather is nice

So there is no missing word in Arabic; the sentence is complete as it stands.

Both orders are possible in Arabic, but they give slightly different emphasis.

The given sentence:

• ضغط الدم ودرجة الحرارة على الشاشة

starts with the thing being talked about, then says where it is:

• Blood pressure and temperature are on the screen

If you said:

• على الشاشة ضغط الدم ودرجة الحرارة

that would put more emphasis on the location:

• On the screen are the blood pressure and temperature

So the original order is neutral and natural, especially in a practical or descriptive context.

These are both examples of the iḍāfa construction, often called the genitive or possessive construction.

1. ضغط الدم

Literally:

• ضغط = pressure
• الدم = the blood

Together:

• ضغط الدم = blood pressure
• literally the pressure of the blood

2. درجة الحرارة

Literally:

• درجة = degree
• الحرارة = the heat / temperature

Together:

• درجة الحرارة = temperature
• literally degree of heat

In an iḍāfa:

• the first noun usually does not take الـ
• the second noun often shows definiteness

That is why you get:

• ضغط الدم
• not الضغط الدم

and

• درجة الحرارة
• not الدرجة الحرارة in this structure

على means on, while في means in.

So:

• على الشاشة = on the screen
• في الشاشة would literally be in the screen, which usually does not fit the meaning here

When information is displayed, Arabic commonly uses على:

• على الشاشة = on the screen
• على الهاتف = on the phone
• على الموقع = on the website

So this is the normal preposition for something appearing on a display.

Yes. لدي is also correct.

Both can mean I have:

• عندي سعال
• لدي سعال

The difference is mostly one of style:

• عندي is very common and natural in everyday use
• لدي often sounds a bit more formal or written

In medical or formal contexts, both are possible. A learner should understand both, but عندي is extremely useful in ordinary speech and basic MSA.

الـ is the definite article, equivalent to the.

So:

• الدم = the blood
• الحرارة = the heat / the temperature
• الشاشة = the screen

In the sentence, these definite nouns are natural because the phrases are specific:

• ضغط الدم = blood pressure
• درجة الحرارة = temperature
• على الشاشة = on the screen

A learner should notice that Arabic uses definiteness a lot inside set expressions and iḍāfa phrases.

In full formal MSA, these words can have case endings, but they are usually not written in ordinary text.

For example, in fully vowelled formal Arabic, you might see forms like:

• عندي سعالٌ
• ضغطُ الدمِ
• على الشاشةِ

But in normal modern writing, short vowels and case endings are usually omitted. Native readers understand them from context.

So for most learners, the important thing is:

• recognize the structure
• learn the vocabulary
• do not worry if the case endings are not written

They exist in formal grammar, but everyday written Arabic usually leaves them out.
