این کتاب از آن کتاب آسان تر نیست، و من هنوز آن را نمیفهمم.

In Persian, از is the normal word used to make comparisons. In this pattern, it works like than in English.

So:

• این کتاب = this book
• از آن کتاب = than that book
• آسان‌تر = easier
• نیست = is not

A very common comparison pattern is:

X از Y adjective‌تر است / نیست

For example:

• این خانه از آن خانه بزرگ‌تر است = This house is bigger than that house
• او از من جوان‌تر نیست = He is not younger than me

تر is the comparative suffix in Persian. It usually corresponds to English -er or more.

So:

• آسان = easy
• آسان‌تر = easier

This is one of the most common ways to form comparisons in Persian.

A few examples:

• خوب → بهتر = good → better
• سخت → سخت‌تر = hard → harder
• آسان → آسان‌تر = easy → easier

In careful writing, you will often see a نیم‌فاصله, so the standard form is usually written آسان‌تر rather than آسان تر.

Literally, it means is not easier.

That does not always mean exactly the same thing as is harder. It could mean:

• it is harder
• it is equally easy
• at least, it is not easier

In real context, many people would understand it as suggesting that this book is no easier, and probably still difficult. But grammatically, the sentence only says not easier.

Persian usually places the verb at or near the end of the clause. That is one of the biggest word-order differences from English.

So instead of:

• This book is not easier than that book

Persian naturally says something closer to:

• This book than that book easier not-is

That is why نیست comes at the end.

This verb-final tendency is very common in Persian.

These are demonstratives:

• این = this
• آن = that

So:

• این کتاب = this book
• آن کتاب = that book

In everyday spoken Persian, آن is very often pronounced or replaced as اون.

So in speech, you may hear:

• این کتاب از اون کتاب آسون‌تر نیست

That is more colloquial, while آن is more formal/written.

Yes, it could be shortened if the meaning is already clear from context. But repeating کتاب makes the comparison very explicit and natural, especially for learners or in careful writing.

So both are possible:

• این کتاب از آن کتاب آسان‌تر نیست
• این کتاب از آن آسان‌تر نیست

The full version is clearer because it explicitly says that book rather than just that one.

هنوز means still or yet, depending on the English translation you choose.

In this sentence:

• من هنوز آن را نمی‌فهمم

it gives the idea of:

• I still do not understand it
• I do not understand it yet

Both are close in meaning. With a negative verb, English may prefer yet in some contexts, but still also works very naturally.

Yes. The ending -م in نمی‌فهمم already shows that the subject is I.

So Persian could simply say:

• هنوز آن را نمی‌فهمم

and that would still mean I still do not understand it.

Adding من can do a few things:

• make the subject clearer
• add emphasis
• create contrast

So من is not strictly necessary here, but it is perfectly normal.

It has several parts:

• نـ = negative marker
• می‌ = ongoing/imperfective present marker
• فهم = present stem of فهمیدن = to understand
• ـم = I

So:

• می‌فهمم = I understand / I am understanding
• نمی‌فهمم = I do not understand

In standard spelling, this is usually written نمی‌فهمم with a نیم‌فاصله after می. Many people also write نمیفهمم in casual typing, but نمی‌فهمم is the standard form.

را marks a specific direct object. It is one of the most important particles in Persian grammar.

Here, آن را means that / it as a definite object, referring back to the book or its content.

So:

• آن را نمی‌فهمم = I do not understand it

You can think of را as a marker that tells you: this noun or pronoun is the direct object of the verb.

Compare:

• کتاب می‌خوانم = I read books / I am reading a book
• کتاب را می‌خوانم = I am reading the book

Persian often uses demonstratives for third-person pronouns, especially in writing.

So آن can mean:

• that
• it
• he / she, in some contexts
• the previously mentioned thing

In this sentence, آن را is best understood as it in English, because it refers back to something already mentioned.

So even though آن literally looks like that, in context it functions very naturally as it.

Almost, but in standard modern Persian orthography, two places are usually written with a نیم‌فاصله:

• آسان‌تر
• نمی‌فهمم

So a more standard written version would be:

این کتاب از آن کتاب آسان‌تر نیست، و من هنوز آن را نمی‌فهمم.

Many typed texts omit the نیم‌فاصله and write:

• آسان تر
• نمیفهمم

You will see both, but the version with نیم‌فاصله is generally preferred in formal writing.

Yes. In everyday speech, many speakers would say something like:

این کتاب از اون کتاب آسون‌تر نیست، و من هنوزم اون رو نمی‌فهمم.

Some common spoken changes are:

• آن → اون
• آسان → آسون
• را → رو
• هنوز may become هنوزم for a conversational tone

So the written sentence is correct and natural, but the spoken version often sounds a bit different.
