من آخر کلاس با استادم صحبت کردم.

من is not necessary in most contexts.

Persian verbs usually show the subject clearly, and کردم already means I did, so the listener can understand that the subject is I even if من is omitted.

So both are possible:

• من آخر کلاس با استادم صحبت کردم.
• آخر کلاس با استادم صحبت کردم.

Using من can add a little emphasis or contrast, like I talked to my teacher.

آخر کلاس means the end of class or at the end of class.

• آخر = end, last part
• کلاس = class

So literally it is something like end of class.

In natural English, you would usually translate it as:

• at the end of class
• at the end of the lesson

Persian often expresses time phrases without a preposition where English uses one.

So English says:

• at the end of class

But Persian can simply say:

• آخر کلاس

This kind of time expression works adverbially by itself in the sentence.

Yes, there is an ezafe relationship here, even though it is usually not written in normal Persian script.

So آخر کلاس is pronounced roughly like:

• âkhar-e کلاس / âkhar-e kelâs

That -e connects آخر to کلاس, just like in many Persian noun phrases.

So grammatically, think of it as:

• آخرِ کلاس = the end of the class

The ezafe is often omitted in writing unless needed for clarity.

Because the verb expression صحبت کردن often uses با to mark the person you talk with.

• با = with
• با استادم = with my teacher

So:

• با استادم صحبت کردم = I talked with my teacher

In English, we often say talked to my teacher or talked with my teacher, but in Persian با is very common with this structure.

استادم means my teacher.

It is made of:

• استاد = teacher, professor, instructor
• ـم = my

So:

• استاد + م = استادم
• استادم = my teacher

This ـم is a possessive ending attached directly to the noun.

Some related examples:

• کتابم = my book
• دوستم = my friend
• استادم = my teacher

This is a compound verb, which is very common in Persian.

• صحبت = conversation, speaking
• کردم = I did

So literally it is something like I did conversation, but naturally it means:

• I talked
• I had a conversation

This pattern is extremely common in Persian:

• noun + کردن
• adjective + کردن
• other element + کردن

For example:

• کار کردم = I worked
• فکر کردم = I thought
• صحبت کردم = I talked

So you should learn صحبت کردن as a full verb meaning to talk / to speak.

کردم is the simple past form of کردن for I.

Breakdown:

• کرد = did
• ـم = I

So:

• کردم = I did

Inside the compound verb صحبت کردم, it gives the whole sentence a past meaning:

• I talked
• I spoke

Because Persian normally follows Subject–Object/Complement–Verb order, with the main verb at the end.

So this sentence is structured like:

• من = I
• آخر کلاس = at the end of class
• با استادم = with my teacher
• صحبت کردم = talked

This final-verb pattern is one of the most important word-order features in Persian.

Because there is no direct object here.

را is used for a specific direct object, but صحبت کردن in this sentence does not take a direct object. Instead, the person involved is introduced with با:

• با استادم صحبت کردم = I talked with my teacher

So استادم is not a direct object here. It is part of a prepositional phrase.

Yes, Persian word order is somewhat flexible, as long as the verb stays near the end and the sentence remains clear.

For example, these are all possible depending on emphasis:

• من آخر کلاس با استادم صحبت کردم.
• من با استادم آخر کلاس صحبت کردم.
• آخر کلاس با استادم صحبت کردم.

The original version is very natural, but other orders can be used to highlight time, person, or topic.

No. A very common everyday alternative is:

• با استادم حرف زدم.

That also means I talked to/with my teacher.

Very roughly:

• صحبت کردن can sound a bit more neutral or slightly more formal
• حرف زدن is very common and conversational

Both are natural, but صحبت کردم is completely standard.

Persian does not have articles exactly like English a/an and the.

So nouns often appear without any article word:

• کلاس = class / the class / a class, depending on context
• استادم = my teacher

In this sentence, context makes it clear that کلاس refers to the relevant class, so English naturally translates it as the class or just class, depending on the wording.
