خواهرم پیشنهاد داد که فردا با هم به فروشگاه برویم.

خواهرم means my sister.

It is made of:

• خواهر = sister
• -م = my

In Persian, possessive endings are often attached directly to the noun, so instead of a separate word for my, you can simply add -م.

Other examples:

• برادرم = my brother
• دوستم = my friend
• کتابم = my book

Because Persian very often uses enclitic possessive endings instead of separate possessive words.

So:

• خواهرم = my sister
• خواهرت = your sister
• خواهرش = his/her sister

This is extremely common and natural in Persian. A native English speaker may expect something like my + sister, but Persian often packs that meaning into one word.

پیشنهاد داد means suggested.

Literally:

• پیشنهاد = suggestion / proposal
• داد = gave

So word-for-word, it is something like gave a suggestion, but in normal English we translate it as suggested.

This is a very common Persian pattern: a noun + light verb combine to make one verbal meaning.

Examples of similar patterns:

• تصمیم گرفت = decided (literally took a decision)
• تلفن کرد = called / phoned
• کمک کرد = helped

So پیشنهاد داد should be learned as a unit meaning to suggest.

Yes, پیشنهاد کرد is also used and also means suggested.

However, پیشنهاد دادن is very common and natural. In this sentence, پیشنهاد داد is perfectly standard.

So a learner should know both patterns exist:

• پیشنهاد دادن
• پیشنهاد کردن

Both can mean to suggest / to make a suggestion.

که means that here.

It introduces the content of the suggestion:

• خواهرم پیشنهاد داد که...
• My sister suggested that...

So the part after که explains what she suggested:

• فردا با هم به فروشگاه برویم
• that we go to the store together tomorrow

In English, that is sometimes omitted, but in Persian که is very common in this structure.

Because Persian usually puts the verb at the end of the clause.

So in the clause:

• فردا با هم به فروشگاه برویم

the verb برویم comes last.

This is very normal Persian word order. English speakers often want to place the verb earlier, but Persian typically keeps it near the end, especially in subordinate clauses like this one.

برویم is the first person plural subjunctive form of رفتن (to go), and here it means that we go / let’s go depending on context.

Breakdown:

• رو = present stem of رفتن
• بـ = subjunctive prefix
• -یم = we

So:

• برویم = we go / that we go

After verbs like suggest, Persian commonly uses the subjunctive in the following clause. That is why برویم is used here.

The ending -یم shows first person plural, meaning we.

So Persian does not need to say ما (we) explicitly here, because the verb ending already tells you the subject.

That is why the sentence does not need an extra ما before برویم.

Yes, it could:

• خواهرم پیشنهاد داد که فردا با هم به فروشگاه ما برویم

But that sounds unnecessary in most contexts because -یم already shows the subject is we.

Persian often drops subject pronouns when the verb ending makes the subject clear. So the original sentence sounds more natural.

با هم means together or literally with each other.

Here it shows that the speaker and the sister would go together:

• فردا با هم به فروشگاه برویم
• that we go to the store together tomorrow

This is a very common expression in Persian.

It could be omitted if the context already makes it clear, but including it emphasizes that the action is done together.

Compare:

• به فروشگاه برویم = that we go to the store
• با هم به فروشگاه برویم = that we go to the store together

So با هم adds an important nuance, not just extra words.

به here means to and marks direction or destination.

So:

• به فروشگاه = to the store

This is the normal preposition used with many motion verbs in Persian.

Examples:

• به خانه رفت = he/she went home
• به مدرسه می‌روم = I go to school
• به فروشگاه برویم = let’s go / that we go to the store

فروشگاه means store, shop, or sometimes store/market depending on context.

It is a standard word and can sound a bit more neutral or slightly formal than some everyday alternatives.

In casual speech, people also often say:

• مغازه = shop
• فروشگاه = store

So فروشگاه is perfectly correct and natural here.

Persian word order is flexible, but the original order is very natural:

• فردا = tomorrow
• با هم = together
• به فروشگاه = to the store
• برویم = we go

So the sentence moves from time to manner/companionship to destination to verb.

Other orders are possible, but the given one is smooth and common.

A careful pronunciation would be approximately:

khâharam pishnehâd dâd ke fardâ bâ ham be forushgâh beravim

A more natural spoken pronunciation may sound closer to:

khâharam pishnehâd dâd ke fardâ bâ ham be forushgâh berim

A few notes:

• خواهرم = khâharam
• پیشنهاد = pishnehâd
• فردا = fardâ
• برویم in speech is often closer to berim

Not always. In careful or formal Persian, the written form برویم may be pronounced more fully, but in everyday speech it often becomes something closer to بریم (berim).

So learners should know the difference between:

• written / formal: برویم
• common spoken: بریم

This kind of difference between written and spoken Persian is very common.

It is neutral and perfectly natural, but it leans a bit toward standard written or careful spoken Persian, especially because of برویم.

In everyday conversation, someone might more casually say:

• خواهرم پیشنهاد داد که فردا با هم بریم فروشگاه.

That said, the original sentence is absolutely normal and useful to learn.

Very roughly, the structure is:

• خواهرم = my sister
• پیشنهاد داد = suggested
• که = that
• فردا = tomorrow
• با هم = together
• به فروشگاه = to the store
• برویم = we go

So the literal order is something like:

My sister suggested that tomorrow together to the store we go.

That sounds odd in English, but it is normal Persian structure. This is a good example of how Persian often keeps the verb until the end.
