لو نسيت كلمة السر، افتحي التطبيق وشوفي الرسالة.

لو means if.

In Egyptian Arabic, لو is the most common everyday way to introduce a condition:

• لو نسيت... = If you forget / if you forgot...

A native English speaker may have seen إذا in Standard Arabic, but in Egyptian speech لو is much more natural and common.

This is very normal in Arabic.

After لو, Arabic often uses a past form even when the meaning is present or future in English. So:

• لو نسيت كلمة السر
  literally: if you forgot the password
  natural meaning: if you forget the password

So the past form here does not force a past-time meaning. It is just a common conditional structure.

Because of the two imperatives:

• افتحي = open (said to one woman)
• شوفي = see/check (said to one woman)

The ending -ي here marks the feminine singular imperative in Egyptian Arabic.

So the speaker is talking to one female person.

Because Arabic spelling often does not show all the short vowels.

The form نسيت can represent different meanings depending on context. In this sentence, the later verbs افتحي and شوفي make it clear that the addressee is female, so we understand نسيت here as if you (f.) forgot.

In fully vowelled writing, the distinction would be clearer. In informal Egyptian writing, some people may also spell it more phonetically, but in normal Arabic script this kind of ambiguity is very common.

Literally, كلمة السر means the word of the secret.

But as a fixed expression, it means password.

This is an idafa structure, also called a construct phrase:

• كلمة = word
• السر = the secret

Together:

• كلمة السر = password

Arabic often makes compounds this way instead of using one single word.

They are both imperatives:

• افتحي from فتح / يفتح = to open
• شوفي from شاف / يشوف = to see, look, check

For a female singular addressee, Egyptian commonly adds -ي to the imperative:

• masculine singular: افتح / شوف
• feminine singular: افتحي / شوفي
• plural: افتحوا / شوفوا

So the sentence could be changed depending on who is being addressed.

Literally, yes, it comes from the verb to see/look.

But in real Egyptian usage, شوف and شوفي are very flexible and often mean:

• look at
• check
• see
• have a look at

So in this sentence, شوفي الرسالة is more natural in English as:

• check the message
• look at the message

not just the literal see the message.

The و simply means and.

It links the two actions:

• افتحي التطبيق = open the app
• وشوفي الرسالة = and check the message

In Egyptian Arabic, chaining commands with و is very common and sounds natural.

Because they are definite: the speaker means a specific app and a specific message.

• التطبيق = the app
• الرسالة = the message

Even if English sometimes says open an app or check a message, Arabic here is assuming the listener knows which app and which message are meant.

Not necessarily.

الرسالة can mean:

• message
• text message
• notification
• email message
• system message

The exact meaning depends on context. Since the sentence mentions an app and a password, it could easily mean a verification message, reset message, or in-app notification.

To one man, it would be:

• لو نسيت كلمة السر، افتح التطبيق وشوف الرسالة.

Changes:

• افتحي → افتح
• شوفي → شوف

To a group, you would usually say:

• لو نسيتوا كلمة السر، افتحوا التطبيق وشوفوا الرسالة.

So the imperative endings are one of the clearest places where Arabic shows who is being addressed.

It is clearly Egyptian-style or at least colloquial in feel.

The biggest clue is شوفي from يشوف, which is very common in spoken Arabic, including Egyptian. Also, لو is extremely common in speech for if.

A more Standard Arabic version might use different wording, especially for شوفي, such as a verb closer to look at or check in formal language.

So a learner should read this sentence as everyday spoken Arabic, not high formal Arabic.
