اگر هفته بعد وقت داری، با من به کتابخانه بیا.

A natural breakdown is:

• اگر = if
• هفته بعد = next week
• وقت = time
• داری = you have
• با من = with me
• به کتابخانه = to the library
• بیا = come

So the literal order is roughly:

If next week time you-have, with me to the library come.

That sounds unusual in English, but it is perfectly normal in Persian.

In Persian, وقت داشتن literally means to have time.

• وقت = time
• داشتن = to have
• داری = you have

So وقت داری means you have time / you're free.

This is a very common everyday expression. In English we might say if you're free next week, but Persian often says if you have time next week.

Persian often drops subject pronouns when the verb already makes the subject clear.

Here:

• داری means you have
• بیا is the command come! for you

Because the verb forms already show that the sentence is talking to you, the pronoun تو is unnecessary.

You could include it for emphasis, but normally you would not:

• اگر هفته بعد تو وقت داری... = If you have time next week...

That is possible, but usually less natural unless you want contrast or emphasis.

This is a very common learner question.

• بیا = come
• برو = go

Persian uses come here because the idea is come with me. The speaker is inviting the listener to join them, so the movement is understood relative to the speaker.

So:

• با من ... بیا = come with me ...
• به کتابخانه برو = go to the library

If you say با من به کتابخانه بیا, the feeling is join me and come to the library.

They have different jobs:

• با من = with me
• به کتابخانه = to the library

So:

• با means with
• به means to

In this sentence:

• با من tells you who accompanies you
• به کتابخانه tells you where you are going

That is why both are needed.

Yes. It is singular informal, used with تو.

You can tell because of:

• داری = informal you have
• بیا = informal command come

A polite or plural version would be:

اگر هفته بعد وقت دارید، با من به کتابخانه بیایید.

That would be used for:

• one person politely
• more than one person

Change the verb forms:

• داری → دارید
• بیا → بیایید

So the polite version is:

اگر هفته بعد وقت دارید، با من به کتابخانه بیایید.

This means the same thing, but sounds respectful or plural.

اگر means if.

In this sentence, Persian simply uses normal present-tense forms:

• اگر هفته بعد وقت داری... = If you have time next week...

There is no special conditional verb form here like in some languages. This is a very normal, everyday type of condition.

So Persian often builds simple if sentences like this:

• اگر وقت داری، بیا. = If you have time, come.
• اگر می‌خواهی، برو. = If you want, go.

Because Persian often places time expressions early in the sentence.

So:

• اگر هفته بعد وقت داری... literally = If next week you have time...

This is very natural in Persian. Time expressions commonly come before the main part of the clause.

You could think of the structure as:

If [time expression] [main condition], ...

Yes, Persian is somewhat flexible, though some versions sound more natural than others.

For example:

• اگر هفته بعد وقت داری، با من به کتابخانه بیا.
  Very natural.

You may also hear things like:

• اگر وقت داری، هفته بعد با من به کتابخانه بیا.

That shifts the emphasis a little. It sounds more like:

If you have time, come with me to the library next week.

So the original version is natural because it sets the time frame early.

Usually yes, هفته بعد means next week in everyday speech.

Literally:

• هفته = week
• بعد = after / later / next

Together, هفته بعد means the following week / next week.

In context, it is understood naturally as next week.

A helpful way to see it is:

اگر + time + condition, + with me + to the library + come

More specifically:

1. اگر = if
2. هفته بعد = next week
3. وقت داری = you have time
4. با من = with me
5. به کتابخانه = to the library
6. بیا = come

Persian often puts the verb at the end of the clause, especially in full phrases like this. That is why بیا comes last.

Yes, کتابخانه is one word, meaning library.

It is commonly pronounced roughly like:

ketâb-khâne

A few pronunciation notes:

• kh is the Persian sound خ, like the ch in Scottish loch or German Bach
• â is a long a sound

So the word is not split in normal writing, even though historically it contains parts meaning something like book-house.

The comma separates the if-clause from the main clause:

• اگر هفته بعد وقت داری = if you have time next week
• با من به کتابخانه بیا = come with me to the library

This is similar to English:

If you have time next week, come with me to the library.

In modern Persian writing, punctuation is used quite a lot, especially to make sentences easier to read. The comma here is natural and helpful.

Yes. That is a very natural English translation.

Even though وقت داری literally means you have time, the sense is often:

• if you're free
• if you have time available

And با من به کتابخانه بیا can be rendered as:

• come with me to the library
• come to the library with me

Both are good English translations.

Normally, no. You need به before کتابخانه here.

• به کتابخانه = to the library

Without به, the sentence sounds incomplete or incorrect in standard Persian for this meaning.

So the natural form is:

با من به کتابخانه بیا

not

با من کتابخانه بیا

• داری comes from داشتن = to have
• بیا comes from آمدن = to come

More specifically:

• داری = present form meaning you have
• بیا = imperative form meaning come!

So if you want to learn the verbs behind this sentence, they are:

• داشتن
• آمدن

Yes. Even though بیا is grammatically an imperative, in context it often works as a friendly invitation:

If you have time next week, come with me to the library.

So it does not have to sound harsh. Tone and context matter a lot. In everyday speech, this can sound warm and casual, especially between friends.

If you want to soften it further, Persian also has other ways to make invitations, but this sentence is already very natural and friendly in an informal context.
