اذا نسيت كلمة السر، ابعتلي رسالة.

A simple pronunciation guide is:

iza nseet kelmet es-serr, ibʿatli risaale.

A few notes:

• اذا = iza
• نسيت = nseet
• كلمة السر = kelmet es-serr
• ابعتلي = ibʿatli
• رسالة = risaale

Exact vowels can vary a bit by region, but this is a good Levantine-style pronunciation.

اذا in Levantine Arabic means if. It is very common for real or likely conditions:

• اذا وصلت، خبرني = If you arrive, let me know
• اذا نسيت كلمة السر، ابعتلي رسالة = If you forget the password, send me a message

It is the normal choice here.

Both can be translated as if, but they are not always interchangeable.

• اذا usually introduces a normal, real, or likely condition.
• لو often sounds more hypothetical, less expected, or sometimes counterfactual depending on context.

So in this sentence, اذا fits naturally because forgetting a password is a real possibility.

This is a very common Arabic pattern.

After اذا, Levantine often uses the past/perfect form even when the meaning is present or future in English. So:

• اذا نسيت can mean if you forget
• It does not have to mean only if you forgot

English and Arabic handle conditionals differently here. So this is normal, natural Levantine.

Arabic often drops subject pronouns because the verb usually carries that information.

So instead of saying something like if you forgot, Arabic can simply say:

• نسيت = you forgot / you forget in this context

Also, the second part is a command:

• ابعتلي = send me

That makes it even clearer that the sentence is addressing you.

ابعتلي has two parts:

• ابعت = send!
• لي = to me

Together:

• ابعتلي = send me or more literally send to me

This kind of attached pronoun is extremely common in spoken Arabic.

That initial ا helps make the imperative easier to pronounce.

The verb is related to يبعت = he sends / to send.
The imperative becomes:

• ابعت = send!

In spoken Arabic, an extra helping vowel is often added at the beginning of imperatives like this.

Literally, كلمة السر means:

• كلمة = word
• السر = the secret

So word-for-word it is the word of the secret, but the natural English meaning is password.

This is an idafa construction, a very common Arabic noun pattern:

• first noun: كلمة
• second noun: السر

The first noun usually does not take ال, and the second noun makes the whole phrase definite.

Because the meaning is a message, not the message.

• رسالة = a message
• الرسالة = the message

So ابعتلي رسالة means send me a message, in a general sense.

Yes. ابعتلي is the imperative to one person.

In teaching materials, this form is often treated as the basic singular form. If you want to be more specific:

• to one man: ابعتلي
• to one woman: ابعتيلي
• to more than one person: ابعتولي

So the given sentence is speaking to one person.

It is clearly colloquial Levantine, especially because of ابعتلي.

A more Modern Standard Arabic version would be closer to:

• إذا نسيت كلمة السر، أرسل لي رسالة.

What makes the original feel spoken and Levantine is mainly:

• the verb choice and imperative form ابعتلي
• the overall conversational tone

So this is the kind of sentence you could naturally hear in everyday speech.
