وصل صديقي للتو.

وصل is the Arabic perfect/past form, specifically third-person masculine singular: he arrived.

In Arabic, this past form is often used for a completed action, including one that English expresses with the present perfect. Because للتو means just now, the sentence naturally means has just arrived or just arrived.

Because the verb already tells you the subject.

وصل by itself already means he arrived. Arabic often leaves out subject pronouns unless they are needed for emphasis or contrast.

So:

• وصل صديقي للتو = My friend has just arrived
• هو وصل للتو = He has just arrived / He is the one who just arrived

The second version sounds more emphatic.

صديق means friend.

When you add -ي, it becomes صديقي = my friend.

That -ي is a possessive suffix, so Arabic expresses my by attaching it directly to the noun instead of using a separate word.

So:

• صديق = friend
• صديقي = my friend

Because a noun with a possessive suffix is already definite.

In English, friend is indefinite, but my friend is definite. Arabic works similarly. Once you add -ي meaning my, the noun is already specific, so you do not add ال.

So صديقي already means my friend, not just a friend of mine in some vague sense.

Usually yes.

صديق is the masculine word for friend, so صديقي normally means my male friend.

If you mean my female friend, you would usually say صديقتي. The verb would also be feminine:

• وصلت صديقتي للتو = My female friend has just arrived

للتو is a fixed expression meaning just now, a moment ago, or simply just in this kind of sentence.

It is best learned as a chunk:

• وصل للتو = just arrived
• جاء للتو = just came

You do not need to translate it word-for-word every time; it functions as an adverbial expression of very recent time.

Both are possible in Arabic.

• وصل صديقي للتو is a very normal, neutral MSA sentence.
• صديقي وصل للتو is also correct, but it gives a bit more prominence to my friend as the topic.

Arabic often prefers verb-first order in straightforward narration, especially in formal written style.

Because وصل can be used by itself when you simply mean arrived.

You use إلى when you mention the destination:

• وصل صديقي إلى البيت = My friend arrived at the house/home

But if no destination is stated, وصل alone is enough:

• وصل صديقي = My friend arrived

So the sentence is complete as it stands.

Because normal Arabic writing usually leaves out short vowels.

So وصل is written without the little vowel marks that would show the full pronunciation. Learners have to rely on vocabulary and context. In this sentence, the intended reading is the common past-tense verb waṣala = arrived.

This is completely normal in Arabic. As you learn more words and patterns, reading unvocalized text becomes much easier.

A careful reading is roughly:

waṣala ṣadīqī li-t-taww

A few pronunciation notes:

• ص in صديقي is an emphatic s
• ق in صديق is a deep q sound, not an English k
• In للتو, the ت is doubled in pronunciation

So the rhythm is roughly:

wa-ṣa-la ṣa-dī-qī li-t-taww

In natural speech, exact final short vowels may be reduced or not clearly heard.
