من هم این پیشنهاد را دوست دارم، اما هنوز تصمیم نگرفته ام.

من هم means I too / me too / I also.

In Persian, هم usually comes after the word it adds the meaning of also/too to.

So:

• من هم = I too
• او هم = he/she too
• این پیشنهاد هم = this proposal too

In this sentence, هم is attached to من because the speaker is saying I also like the proposal.

Persian often omits the subject pronoun because the verb ending already shows the person.

So:

• این پیشنهاد را دوست دارم = I like this proposal

The -م in دارم already means I.

However, in your sentence, من is useful because of هم:

• من هم ... = I also ...

So here من is not just grammatical; it adds emphasis and contrast.

In casual speech, من هم is often shortened to منم:

• منم این پیشنهاد رو دوست دارم = I also like this proposal

را marks a specific direct object.

Here, این پیشنهاد means this proposal/suggestion, which is definite and specific, so Persian normally uses را:

• این پیشنهاد را دوست دارم

A very literal breakdown is:

• این پیشنهاد = this proposal
• را = object marker
• دوست دارم = I like

In everyday speech, را is usually pronounced رو:

• این پیشنهاد رو دوست دارم

So:

• formal/written: را
• spoken: رو

دوست داشتن is the normal Persian verb for to like / to love.

So:

• دوست دارم = I like / I love, depending on context

With things like books, ideas, food, or proposals, it usually means like:

• این فیلم را دوست دارم = I like this film
• این پیشنهاد را دوست دارم = I like this proposal

A more formal alternative for like/approve of is:

• می‌پسندم = I approve of / I like

So این پیشنهاد را می‌پسندم is possible, but دوست دارم is very common and natural.

Persian usually follows Subject – Object – Verb order.

So this sentence is structured like:

• من هم = I also
• این پیشنهاد را = this proposal
• دوست دارم = like

Literally, Persian is closer to:

• I also this proposal like

This is normal in Persian. The verb typically comes near the end of the clause.

The second part works the same way:

• اما هنوز تصمیم نگرفته‌ام
• literally: but still decision not-taken-have-I

So the verb idea comes at the end again.

Persian often uses compound verbs.
Here the expression is:

• تصمیم گرفتن = to decide
• literally: to take a decision

So:

• تصمیم گرفتم = I decided
• تصمیم نگرفته‌ام = I have not decided

The second part breaks down like this:

• تصمیم = decision
• نگرفته‌ام = I have not taken

So literally it means:

• I have not taken a decision

But in natural English, that is simply:

• I haven’t decided

نگرفته‌ام is the present perfect negative form:
I have not taken / I haven’t taken

Because تصمیم گرفتن means to decide, this becomes:

• هنوز تصمیم نگرفته‌ام = I still haven’t decided / I haven’t decided yet

This form is very natural when the decision is still unresolved up to now.

Compare:

• تصمیم نمی‌گیرم = I do not decide / I am not deciding
  
  • this sounds more habitual or less suitable here
• تصمیم نگرفتم = I didn’t decide
  
  • simple past
• تصمیم نگرفته‌ام = I haven’t decided
  
  • the most natural match here

So نگرفته‌ام fits the idea of up to now, no decision has been made by me.

هنوز means still or yet, depending on the translation.

In a negative sentence like this, English often uses yet:

• هنوز تصمیم نگرفته‌ام = I haven’t decided yet

But a very literal sense is closer to still:

• I still haven’t decided

Its position is fairly flexible, but placing it before the verb phrase is very common:

• هنوز تصمیم نگرفته‌ام

That sounds completely natural.

The more standard modern spelling is:

• نگرفته‌ام

with a half-space before ام.

But many texts, messages, or learners’ materials write it with a normal space:

• نگرفته ام

Both mean the same thing. The difference is mostly orthographic.

The ending -ام is the I ending here:

• گرفته‌ام = I have taken
• نگرفته‌ام = I have not taken

So if you see نگرفته ام, understand it as the same form.

Both are correct.

• اما = but
• ولی = but

اما is a bit more formal or written in tone.
ولی is very common in everyday speech.

So your sentence is natural as written:

• من هم این پیشنهاد را دوست دارم، اما هنوز تصمیم نگرفته‌ام.

A more conversational version would be:

• منم این پیشنهاد رو دوست دارم، ولی هنوز تصمیم نگرفتم / نگرفته‌ام.

So:

• اما = slightly more formal
• ولی = more conversational

A common spoken version would be:

• منم این پیشنهادو دوست دارم، ولی هنوز تصمیم نگرفتم.

Changes you often hear in speech:

• من هم → منم
• را → رو / ـو
• اما → ولی
• نگرفته‌ام may become نگرفتم in casual spoken Persian, depending on style and region

So the written sentence is perfectly good, but spoken Persian often sounds smoother and more compact.
