صديقي يصنع قهوة في البيت كل صباح.

The -ي is the possessive suffix meaning my.

So:

• صديق = friend
• صديقي = my friend

This is very common in Arabic. Instead of using a separate word for my, Arabic often attaches it directly to the noun.

Examples:

• كتابي = my book
• بيتي = my house
• صديقي = my friend

In pronunciation, صديقي is roughly ṣadīqī.

Yes. يصنع means he makes or he manufactures/produces.

It comes from the verb:

• صنع = to make

In this sentence, يصنع قهوة means makes coffee.

That said, a learner should know that for drinks or food, Arabic speakers often use other verbs too, such as:

• يُعِدّ = he prepares
• يُحَضِّر = he prepares
• يعمل = sometimes used in some varieties for makes/does

So the sentence is understandable and grammatical, but in very natural usage, يُعِدّ قهوة or يُحَضِّر قهوة may also sound very common.

Yes. يصنع is in the imperfect form, which often corresponds to the present tense in English.

Depending on context, the Arabic imperfect can mean:

• he makes
• he is making
• he will make

The phrase كل صباح = every morning tells you this is a repeated, habitual action.

So here:

• صديقي يصنع قهوة كل صباح = My friend makes coffee every morning

Without context, يصنع is more general. The time phrase clarifies the meaning.

Because here قهوة means coffee in a general, indefinite sense, like some coffee or simply coffee as a drink.

So:

• قهوة = coffee
• القهوة = the coffee

In English, we often just say makes coffee without the, and Arabic does something similar here.

If you said القهوة, it would usually refer to a specific coffee already known from context:

• He makes the coffee

But قهوة here is the normal choice for the general idea.

In fully vocalized formal Arabic, yes, there would normally be a case ending.

Since قهوة is the direct object of يصنع, it would be:

• قهوةً

So the fully vocalized sentence would be:

• صديقي يصنع قهوةً في البيت كل صباح.

However, in normal Arabic writing, short vowel endings are usually not written. So you typically just see:

• قهوة

This is completely normal.

In Arabic, في البيت literally means in the house or in the home, but it very often corresponds to natural English at home.

So:

• في البيت = at home / in the house

Arabic commonly uses the definite article ال here because the meaning is something like the home/house, referring to the familiar home setting.

If you said:

• في بيت
  that would usually mean in a house or in some house, which is less natural here.

Arabic allows more than one word order.

This sentence uses:

• Subject + Verb + Object
• صديقي يصنع قهوة

But Arabic can also use:

• Verb + Subject + Object
• يصنع صديقي قهوة

Both are possible.

Very generally:

• صديقي يصنع قهوة puts a bit more focus on my friend
• يصنع صديقي قهوة starts more neutrally with the action

Both are grammatical in Modern Standard Arabic.

كل صباح means every morning.

Breakdown:

• كل = every / each
• صباح = morning

Arabic often uses time expressions like this directly, without a preposition.

So:

• كل صباح = every morning
• كل يوم = every day
• كل أسبوع = every week

In fully vocalized Arabic, this would usually be:

• كلَّ صباحٍ

Here:

• كلَّ is in the accusative as an adverbial expression of time
• صباحٍ is genitive because it comes after كل in an iḍāfa construction

But in normal writing, you usually just see كل صباح.

Yes, depending on context.

The Arabic imperfect verb يصنع does not force a sharp distinction between:

• makes
• is making

English usually chooses one of those more explicitly. Arabic often leaves it to context.

Because of كل صباح, the most natural English translation is the habitual one:

• My friend makes coffee at home every morning

But grammatically, the verb form itself is broad enough to cover present meanings in general.

A fully vocalized version would be:

صَديقي يَصنَعُ قَهوةً في البَيتِ كُلَّ صَباحٍ.

A quick breakdown:

• صَديقي = my friend
• يَصنَعُ = he makes
• قَهوةً = coffee as the direct object
• في البَيتِ = at home / in the house
• كُلَّ صَباحٍ = every morning

This kind of full marking is helpful for study, but most everyday texts will omit these short vowels.

Here is a simple grammatical breakdown:

• صديقي = the subject
• يصنع = the verb
• قهوة = the direct object
• في البيت = a prepositional phrase showing place
• كل صباح = an expression of time

So the structure is basically:

subject + verb + object + place + time

That is a very useful pattern to recognize in Arabic.

Those are three sounds English speakers often need to practice.

• ص in صديقي and صباح
  This is an emphatic s. It is not exactly like English s. Try saying s with a darker, heavier quality.

• ق in صديقي and قهوة
  In careful Modern Standard Arabic, this is a deep q sound made farther back than English k. It is often described as a voiceless uvular stop.

• ح in قهوة and صباح
  This is a strong breathy ḥ sound from the throat, not the ordinary English h.

A rough learner-friendly pronunciation of the whole sentence is:

ṣadīqī yaṣnaʿu qahwa fī l-bayt kulla ṣabāḥ

That is only an approximation, but it helps as a starting point.

It is a good Modern Standard Arabic sentence.

In everyday spoken Arabic, people might express it differently depending on the dialect. For example, the verb for make/prepare coffee may change, and pronunciation will definitely change.

But as MSA, the sentence is clear and useful:

• صديقي يصنع قهوة في البيت كل صباح.

A slightly more idiomatic MSA version for makes coffee might be:

• صديقي يُعِدُّ قهوةً في البيت كل صباح.
• صديقي يُحَضِّر قهوةً في البيت كل صباح.

So your sentence is fine for learning, and it also opens the door to noticing more natural alternatives later.
