هي عادة بتصحى بدري يوم الشغل.

Because in Arabic, the imperfect/present verb for 3rd person feminine singular takes تـ.

So in Egyptian Arabic:

• هي بتصحى = she wakes up
• هو بيصحى = he wakes up

A common beginner surprise is that بتصحى can also mean you wake up when speaking to one man. The pronoun هي removes that ambiguity here.

In Egyptian Arabic, بـ usually marks the present/habitual.

So:

• بتصحى = she wakes up / she wakes up عادةً / habitually
• with عادة in the sentence, the meaning is clearly habitual: she usually wakes up

This بـ is one of the big differences between Egyptian Arabic and Standard Arabic.

It comes from the Egyptian verb صحي / يصحى, which means to wake up.

In this sentence it is intransitive: the subject wakes up herself.

If you want to wake someone up, Egyptian often uses a different verb pattern, such as صحّى / يصحّي.

So:

• هي بتصحى = she wakes up
• هي بتصحّيه = she wakes him up

Here عادة means usually.

Literally, the word is related to habit or custom, but in everyday usage it often works like an adverb meaning usually.

So هي عادة بتصحى... is a very natural way to say she usually wakes up...

It is flexible, but the position in your sentence is very natural:

• هي عادة بتصحى بدري يوم الشغل

You may also hear other orders, depending on emphasis, such as:

• عادة هي بتصحى بدري يوم الشغل
• هي بتصحى بدري يوم الشغل عادة

The original order sounds neutral and conversational.

Yes. بدري means early, and it is a very common everyday Egyptian word.

It is much more colloquial and natural in speech than a more formal word like مبكر.

Examples:

• صحيت بدري = I woke up early
• بدري أوي = very early

Because Arabic often uses time expressions directly, without a preposition that matches English on.

So just as Arabic can say things like:

• يوم الخميس = on Thursday
• بكرة = tomorrow
• النهارده = today

it can also say:

• يوم الشغل = on a workday / on workdays

English needs on, but Arabic often does not.

Literally, يوم الشغل is something like the day of the work or work day.

In Egyptian Arabic, الشغل is the normal everyday word for work / the job, and using it with الـ is very common even when the meaning is general.

So the phrase does not sound overly specific. It naturally means something like:

• on a workday
• when she has work
• on workdays

Because Arabic often uses a singular time expression in a generic way.

With عادة already giving a repeated, habitual sense, يوم الشغل can naturally mean on workdays in English.

If someone wanted to make the plural more explicit, they could also say:

• أيام الشغل = workdays

But يوم الشغل is still very normal and idiomatic.

Yes, very often it can.

Arabic commonly drops subject pronouns when the meaning is clear from context:

• عادة بتصحى بدري يوم الشغل

However, in this particular case, keeping هي is helpful because بتصحى could also mean you wake up when speaking to one man. So هي makes it clearly she.

A rough pronunciation is:

hiyya ʿāda btiṣḥa badri yōm ish-shoghl

A few notes:

• هي is often pronounced roughly hiyya or heyya
• ع in عادة has no exact English equivalent
• ح in بتصحى is a stronger, breathier h
• الشغل is commonly heard as ish-shoghl or esh-shoghl

Exact pronunciation varies a bit by speaker.

A natural negated version would be:

هي عادة ما بتصحاش بدري يوم الشغل.

Egyptian Arabic usually negates present/habitual verbs with ما ... ش around the verb:

• بتصحى = she wakes up
• ما بتصحاش = she doesn’t wake up

So the full sentence means:

• She usually doesn’t wake up early on workdays.
