Tamam, raporu şimdi gönderiyorum.

Because raporu has the definite accusative ending.

The base noun is rapor = report.
In this sentence, the report is a specific, definite object—you are sending the report, not just a report in a general sense.

So:

• rapor = report / a report
• raporu = the report (as a direct object)

The ending here is -(y)I, which changes according to vowel harmony. After rapor, it becomes -u, so:

• rapor + u -> raporu

This is very common in Turkish when the direct object is specific.

It is the accusative case ending.

Turkish often marks a specific direct object with this ending. The four basic forms are:

• -ı
• -i
• -u
• -ü

Which one appears depends on vowel harmony.

Examples:

• kitabı = the book
• evi = the house
• raporu = the report
• günü = the day

So in raporu şimdi gönderiyorum, the ending shows that the report is the thing being sent.

Because this is the present continuous form.

The verb is göndermek = to send.
To make I am sending, Turkish uses the present continuous pattern:

• verb stem + -iyor
  • personal ending

Here:

• gönder- = send
• -iyor = present continuous marker
• -um = I

So:

• gönderiyorum = I am sending

Because of vowel harmony and sound patterns, the present continuous marker appears in forms like:

• -ıyor
• -iyor
• -uyor
• -üyor

It can do both, depending on context.

In Turkish, the present continuous often covers meanings that in English may sound like:

• I am sending it now
• I’m sending it right away
• I’ll send it now

So in a sentence like Tamam, raporu şimdi gönderiyorum, it often implies an action that is happening immediately, even if the English translation might sometimes sound more natural as Okay, I’ll send the report now.

This is very normal in spoken Turkish.

Because şimdi adds emphasis to the time: now.

Even though gönderiyorum already means I am sending, adding şimdi makes it clearer that the action is happening right now / at this moment.

Compare:

• Raporu gönderiyorum. = I am sending the report.
• Raporu şimdi gönderiyorum. = I am sending the report now.

So şimdi is not grammatically required, but it makes the timing more explicit.

Yes, Turkish word order is flexible, but this order is very natural.

The most neutral pattern is often:

• object + time expression + verb

So:

• raporu = the report
• şimdi = now
• gönderiyorum = I am sending

That gives:

• Raporu şimdi gönderiyorum.

Other orders are possible, depending on emphasis:

• Şimdi raporu gönderiyorum. = emphasizes now
• Gönderiyorum raporu. = less neutral, more marked in everyday speech
• Raporu gönderiyorum şimdi. = possible, but sounds more conversational or emphatic

In Turkish, the verb often comes at the end, especially in neutral sentences.

Because Turkish usually does not need subject pronouns when the verb already shows who the subject is.

In gönderiyorum, the ending -um tells us the subject is I.

So:

• (Ben) raporu şimdi gönderiyorum.

Both are possible, but ben is usually omitted unless you want emphasis or contrast.

For example:

• Ben gönderiyorum. = I’m sending it.
  This can imply contrast, like I’m the one sending it.

Tamam is a very common Turkish word meaning things like:

• okay
• all right
• fine
• got it

At the start of this sentence, it works like a natural conversational response. It suggests something like:

• Okay,
• All right,
• Got it,

So Tamam, raporu şimdi gönderiyorum. sounds like a response to a request or reminder.

Not always. Tamam is flexible.

Depending on context, it can mean:

• okay
• fine
• that’s enough
• complete / finished

Examples:

• Tamam. = Okay.
• Tamam mı? = Okay? / Is that clear?
• Bu iş tamam. = This job is done.
• Yeter, tamam! = Enough, okay!

In your sentence, it is clearly the conversational Okay meaning.

Because Turkish dictionaries list verbs in the infinitive form, usually ending in -mek or -mak.

So:

• göndermek = to send

To use the verb in a sentence, you remove the infinitive ending and add the tense/person endings.

Here:

• gönder- = verb stem
• -iyor = present continuous
• -um = I

So:

• gönderiyorum = I am sending

This is the normal way Turkish verbs are built.

Then you would usually drop the accusative ending.

Compare:

• Raporu gönderiyorum. = I am sending the report.
• Rapor gönderiyorum. = I am sending a report / report(s).

The version without the accusative can sound less definite or less specific.

In your sentence, raporu is used because both speaker and listener already know which report is meant.

A simple pronunciation guide is:

• Tamam -> tah-MAHM
• raporu -> rah-poh-ROO
• şimdi -> SHIM-dee
• gönderiyorum -> roughly gurn-deh-ree-YOR-oom

A few helpful points:

• ş sounds like sh
• ö is like the vowel in German schön or French peu, not a regular English o
• ı is a vowel English does not really have; it is a dull, central vowel
• stress in gönderiyorum is strong near -yor

You do not need a perfect English approximation, but recognizing ş, ö, and ı is very useful.

Yes, absolutely.

Because of şimdi and the conversational context, a very natural English translation is:

• Okay, I’m sending the report now.
• Okay, I’m sending the report right now.
• Okay, I’ll send the report now.

All of these can fit, depending on tone and situation. The Turkish sentence itself is natural and slightly immediate, as if the speaker is acting at once.
