اگر شما امروز خسته نیستید، میخواهید با ما به رستوران بیایید؟

اگر means if. It introduces a condition:

اگر شما امروز خسته نیستید
= if you are not tired today

So the whole sentence has this structure:

If you are not tired today, do you want / would you like to come to the restaurant with us?

Persian often uses اگر just like English uses if.

Yes. نیستید already tells you the subject is you plural or formal you singular because of the ending -ید.

So شما is not strictly necessary. It is often included for:

• clarity
• emphasis
• politeness

This means the sentence could also be said without شما:

اگر امروز خسته نیستید، می‌خواهید با ما به رستوران بیایید؟

That would still be correct.

خسته is an adjective meaning tired.
نیستید means you are not.

Together:

خسته نیستید
= you are not tired

This is a very common Persian pattern:

adjective + form of بودن / to be

Examples:

• خوشحال هستید = you are happy
• آماده نیستید = you are not ready

So Persian does use a form of to be here, just like English does.

Because the sentence is negative.

• هستید = you are
• نیستید = you are not

So:

• شما خسته هستید = you are tired
• شما خسته نیستید = you are not tired

In everyday speech, هستید is often dropped in positive sentences, but نیستید usually stays:

• شما خسته‌اید or شما خسته هستید
• شما خسته نیستید

امروز means today. In this sentence it comes before the adjective phrase:

شما امروز خسته نیستید
= you are not tired today

Persian word order is fairly flexible, especially with time expressions like امروز. You could also hear:

اگر شما خسته نیستید امروز...

But the given order is natural and clear. Putting امروز earlier often helps set the time frame right away.

It can mean either, depending on context.

Literally, می‌خواهید means you want or do you want. But in a question like this, especially in an invitation, it often sounds like:

would you like to... ?

So this sentence can feel softer and more polite than a very direct do you want to... ?

The conditional part with اگر... also helps make it sound considerate:

• If you’re not tired today, would you like to come... ?

The standard spelling is می‌خواهید with a half-space or zero-width non-joiner after می.

So the correct formal spelling is:

می‌خواهید

You will often see: میخواهید

That is very common in casual typing, but it is less standard.

The same thing happens with many Persian verbs:

• می‌روم
• می‌بینیم
• نمی‌خواهند

After خواستن meaning to want, Persian normally uses the subjunctive form of the next verb, not the infinitive.

So:

• می‌خواهم بروم = I want to go
• می‌خواهید بیایید = you want / would like to come

Here, بیایید is the subjunctive form of آمدن for you plural/formal you.

This is a very important pattern in Persian:

خواستن + subjunctive verb

Not:

• می‌خواهید آمدن ✘

But:

• می‌خواهید بیایید ✔

No, not in this sentence.

بیایید can be an imperative in other contexts:

• بیایید! = come! / please come!

But here it comes after می‌خواهید, so it is part of the verb phrase:

• می‌خواهید ... بیایید = do you want / would you like to come

So here it is functioning as the subjunctive complement after خواستن, not as a command.

They express two different relationships:

• با ما = with us
• به رستوران = to the restaurant

So:

با shows accompaniment
به shows direction

Together:

با ما به رستوران بیایید
= come with us to the restaurant

Both prepositions are needed because English also has both ideas:

• with us
• to the restaurant

It can be either:

• you plural
• you singular polite/formal

That is because شما and the ending -ید are used for both.

So this sentence could be said:

• to one person politely
• to several people

Context tells you which one is meant.

It sounds neutral to polite.

Reasons:

• it uses شما
• it uses plural/formal verb endings
• the phrasing is considerate because of اگر شما امروز خسته نیستید

In casual spoken Persian, people might say something more like:

اگه امروز خسته نیستی، می‌خوای با ما بیای رستوران؟

That would be for one person informally.

So the original sentence is a good standard, polite version.

Persian often does not use a direct equivalent of English would in this kind of invitation.

Instead, politeness and softness are expressed through:

• context
• intonation
• wording
• the conditional clause with اگر

So می‌خواهید can naturally cover meanings like:

• do you want to
• would you like to

English uses modal verbs like would very often, but Persian often expresses the same idea without a separate word.

A simple way to see it is:

اگر + subject + time + adjective phrase, main verb + prepositional phrases + final verb

More specifically:

اگر = if
شما = you
امروز = today
خسته نیستید = are not tired
می‌خواهید = do you want / would you like
با ما = with us
به رستوران = to the restaurant
بیایید = come

Persian often puts the main action verb near the end, so learners will notice that the sentence ends with بیایید.

In careful standard Persian, it would sound like:

agar shomâ emruz khaste نیستید، mikhâhid bâ mâ be resturân biyâyid?

A few useful pronunciation notes:

• اگر = agar
• شما = shomâ
• امروز = emruz
• خسته = khaste
• نیستید = nistid
• می‌خواهید is often pronounced close to mikhâid or mikhâhid
• بیایید = biyâyid

In everyday speech, some sounds may get shortened a bit, but the written form stays the same.
