خواهرم برای ناهار برنج و مرغ درست میکند.

The -م is a possessive ending meaning my.

So:

• خواهر = sister
• خواهرم = my sister

Persian often attaches possessive words directly to the noun instead of using a separate word like English my.

Other examples:

• برادرم = my brother
• مادرم = my mother
• دوستم = my friend

In Persian, possession is very often shown by adding a suffix to the noun.

So instead of saying something like my sister with two separate words, Persian commonly says:

• خواهرم = my sister

This is completely normal and very common in everyday Persian.

Some common possessive endings are:

• -م = my
• -ت = your (singular, informal)
• -ش = his / her / its
• -مان = our
• -تان = your (plural or formal)
• -شان = their

For example:

• کتابم = my book
• کتابت = your book
• کتابش = his/her book

برای usually means for, and ناهار means lunch.

So برای ناهار literally means for lunch.

In this sentence, it tells us the purpose or occasion of the food: it is being prepared for lunch.

You can compare:

• برای شام = for dinner
• برای صبحانه = for breakfast

Persian word order is flexible, but the usual basic pattern is:

Subject + other information + object + verb

So in this sentence:

• خواهرم = subject
• برای ناهار = purpose/time-related phrase
• برنج و مرغ = object
• درست میکند = verb

That makes the order feel natural in Persian.

English and Persian do not always place phrases in the same positions, so it is best not to translate word-for-word mechanically.

Because Persian is typically an SOV language:

• S = subject
• O = object
• V = verb

So Persian often puts the verb last.

In this sentence:

• خواهرم = subject
• برنج و مرغ = object
• درست میکند = verb

This is one of the biggest differences from English, which is usually SVO:

• My sister cooks rice and chicken

But Persian prefers:

• My sister rice and chicken cooks/makes

Here درست میکند means something like makes, prepares, or cooks.

The verb comes from درست کردن, which literally means to make / prepare / fix.

When talking about food, درست کردن often means:

• to make
• to prepare
• sometimes naturally in English, to cook

So in this sentence, درست میکند is best understood as prepares/cooks.

Persian often uses درست کردن very naturally for preparing food.

So a Persian speaker may say something that literally looks like make rice and chicken, but in natural English that may become cook rice and chicken or prepare rice and chicken.

This is normal. Languages do not divide meaning in exactly the same way.

Depending on context, درست کردن can mean:

• make
• prepare
• fix
• arrange

With food, it commonly means prepare/cook.

میکند (more formally written می‌کند) is the present tense form meaning he/she does/makes.

In this sentence, because the subject is خواهرم (my sister), it means:

• she makes
• she prepares
• she cooks

The verb is built from:

• میـ = present/imperfective marker
• کند = does/makes

Together:

• می‌کند = she/he does, makes

In context, this can often express a habitual or regular action:

• My sister cooks rice and chicken for lunch.

Depending on context, Persian simple present can sometimes also sound more general than strictly right-now English present.

Because Persian often does not need subject pronouns when the subject is already clear.

Here the sentence already has the subject:

• خواهرم = my sister

So there is no need to add او (she/he).

Even when there is no noun subject, Persian often drops pronouns because the verb ending helps show the person.

For example:

• می‌کنم = I do
• می‌کنی = you do
• می‌کند = he/she does

So Persian often leaves pronouns unstated unless they are needed for emphasis or clarity.

Good question. را usually marks a specific direct object.

But in this sentence, برنج و مرغ is being used in a more general / non-specific way, like rice and chicken as food being prepared, not necessarily a particular identified rice and a particular identified chicken.

So leaving out را sounds natural.

Compare the idea:

• برنج و مرغ درست می‌کند = she cooks rice and chicken
• برنج و مرغ را درست می‌کند = she cooks/prepares the rice and chicken

The version with را sounds more definite/specific, as if both speaker and listener know exactly which rice and chicken are meant.

Grammatically, it simply means rice and chicken.

That could refer to:

• two foods being prepared together
• a meal consisting of rice and chicken
• possibly a combined dish, depending on context

The sentence itself does not force only one interpretation. It just says those two food items are being prepared for lunch.

و means and.

So:

• برنج و مرغ = rice and chicken

It works like English and, joining two nouns together.

In pronunciation, و is usually pronounced like o:

• برنج و مرغ ≈ berenj o morgh

A common pronunciation would be:

khâharam barâye nâhâr berenj o morgh dorost mikonad

Word by word:

• خواهرم = khâharam
• برای = barâye
• ناهار = nâhâr
• برنج = berenj
• و = o
• مرغ = morgh
• درست میکند = dorost mikonad

A more standard spelling of the verb is می‌کند, but pronunciation is the same.

The standard modern spelling is:

• می‌کند

with a small joining mark called a zero-width non-joiner between می and کند.

But many people type it informally as:

• میکند

Both are understood, but می‌کند is the more standard written form.

You may also see this with many other verbs:

• می‌رود
• می‌خورد
• می‌بیند

Informal typing often drops that special spacing.

Usually, by itself, می‌کند is best understood as a simple present / habitual form, like:

• she makes
• she cooks

If you want to clearly say is cooking right now, Persian often uses داشتن:

• خواهرم دارد برای ناهار برنج و مرغ درست می‌کند.
• My sister is making/cooking rice and chicken for lunch.

That said, in some contexts, the simple present can still be understood more broadly, depending on what is happening in the conversation.

In most learner contexts, ناهار simply means lunch.

It refers to the midday meal. So برای ناهار is naturally for lunch.

It does not usually need an article in Persian, so there is no separate word for the lunch or a lunch here unless the context makes that necessary.

The structure is:

خواهرم | برای ناهار | برنج و مرغ | درست میکند

Which breaks down as:

• خواهرم = subject: my sister
• برای ناهار = phrase: for lunch
• برنج و مرغ = object: rice and chicken
• درست میکند = verb: makes/prepares/cooks

So a very literal order would be:

My sister for lunch rice and chicken prepares.

That is why the natural English translation changes the word order even though the meaning stays the same.
