دوستم پیشنهاد داد که بعد از کار با هم شام بخوریم.

In دوستم, the -م at the end means my.

• دوست = friend
• دوستم = my friend

This is a very common pattern in Persian:

• کتابم = my book
• خانه‌ام = my house
• استادم = my teacher

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

Yes. پیشنهاد داد is a compound verb, which is extremely common in Persian.

• پیشنهاد = suggestion / proposal
• داد = gave

Literally, it looks like gave a suggestion, but together it means suggested.

Persian uses many of these noun + verb combinations instead of a single simple verb. For example:

• تصمیم گرفت = decided
• تماس گرفت = contacted / called
• کمک کرد = helped

So in this sentence, پیشنهاد داد should be understood as one verbal idea: suggested.

که introduces the clause that follows the suggestion. Here it works like that in English:

• دوستم پیشنهاد داد که...
• My friend suggested that...

In natural English, that is often omitted, but in Persian که is very common and natural in this kind of sentence.

So the sentence structure is roughly:

• دوستم پیشنهاد داد = my friend suggested
• که بعد از کار با هم شام بخوریم = that we eat dinner together after work

Because after verbs like suggest, Persian often uses the subjunctive.

بخوریم comes from خوردن = to eat, and here it means that we eat / let’s eat / we should eat, depending on context.

Breakdown:

• خور = present stem
• بـ = subjunctive marker
• -یم = we

So بخوریم = that we eat / let us eat

After verbs like these, Persian often uses this pattern:

• پیشنهاد داد که برویم = suggested that we go
• خواست که بمانیم = wanted us to stay
• لازم است که شروع کنیم = it is necessary that we start

So بخوریم is not just plain present tense. It is the form Persian normally uses here.

Because Persian verb endings usually show the subject clearly, so the pronoun is often omitted.

In بخوریم, the ending -یم tells you the subject is we.

Examples:

• بخورم = I eat / that I eat
• بخوری = you eat
• بخورد = he/she eats
• بخوریم = we eat
• بخورید = you all eat / formal you eat
• بخورند = they eat

So Persian does not need a separate word like ما every time. If you said ما بخوریم, it would add emphasis, but it is not necessary.

It means after work.

Breakdown:

• بعد از = after
• کار = work

So:

• بعد از کار = after work

This is a fixed and very common structure in Persian. You can use it with many nouns:

• بعد از کلاس = after class
• بعد از شام = after dinner
• بعد از فیلم = after the movie

Notice that Persian does not need an article here. English says after work, and Persian simply says بعد از کار.

Good question. بخوریم already tells us the subject is we, but با هم adds the idea of together / with each other.

• با = with
• هم = each other / together

So با هم means together.

Compare:

• شام بخوریم = we eat dinner
• با هم شام بخوریم = we eat dinner together

It is not required for grammar, but it adds an important nuance: the friend is suggesting a shared activity.

Yes. Persian commonly uses خوردن = to eat with meals.

• شام خوردن = to have/eat dinner
• ناهار خوردن = to have/eat lunch
• صبحانه خوردن = to have/eat breakfast

This is very normal Persian. English also says eat dinner, so this part matches English quite well.

Also, شام specifically means the evening meal, so here it is dinner.

Persian usually follows Subject – Object/Complements – Verb, with the main verb often coming at the end of its clause.

Here is the sentence in chunks:

• دوستم = my friend
• پیشنهاد داد = suggested
• که = that
• بعد از کار = after work
• با هم = together
• شام = dinner
• بخوریم = we eat

A more literal order would be:

My friend suggested that after work together dinner we eat.

That sounds odd in English, but it is natural Persian word order.

Also notice that the subordinate clause ends with the verb بخوریم, which is very typical in Persian.

Yes, absolutely.

Persian has که, which corresponds to that, but in English the most natural translation is often:

• My friend suggested we have dinner together after work.

You could also say:

• My friend suggested that we have dinner together after work.

Both are fine in English. The Persian sentence naturally includes که, but English does not have to.

Yes, it is natural and standard.

It sounds like normal everyday Persian:

• دوستم = my friend
• پیشنهاد داد = suggested
• بعد از کار = after work
• با هم شام بخوریم = that we have dinner together

It is neither overly formal nor slangy. You could use it in ordinary conversation and in writing.

A slightly more conversational alternative might be:

• دوستم گفت بعد از کار با هم شام بخوریم.

That is closer to My friend said we should have dinner together after work, but your original sentence is perfectly natural and clear.

A common pronunciation is:

dustam pishnehād dād ke ba’d az kār bā ham shām bokhorim

A few notes:

• دوستم sounds like dustam
• پیشنهاد is pronounced roughly pish-nehād
• داد = dād
• بعد از often sounds like ba’d az
• بخوریم = bokhorim

In normal speech, the sentence flows smoothly, and که بعد از کار may sound quite connected.
