لما صحيت، غسلت وشي وشربت ميه باردة.

A natural Egyptian Arabic pronunciation is roughly:

Lamma saḥeet, ḡasalt wishi wi shiribt mayya bārda.

A more English-friendly version:

LAM-ma sa-HEET, gha-SALT WI-shi wi shi-RIBT MAY-ya BAR-da

A few notes:

• ح in صحيت is a strong breathy h sound.
• غ in غسلت is often like a French/German r sound, or a gargled gh.
• ج does not appear here, but in Egyptian Arabic it is often pronounced g.
• Short vowels are often not written in Arabic script, so pronunciation has to be learned.

Here لما means when.

So:

• لما صحيت = when I woke up

In Egyptian Arabic, لما is very commonly used to introduce a time clause:

• لما جيت = when I came
• لما شفته = when I saw him

In this sentence, it sets up the first action, and then the rest tells what happened after that.

Because the verb already shows the subject.

In Egyptian Arabic, past-tense verbs often include endings that tell you who did the action. In this sentence:

• صحيت = I woke up
• غسلت = I washed
• شربت = I drank

The ending -ت marks the speaker here, so أنا is not necessary.

You can say أنا for emphasis:

• أنا صحيت = I woke up / I’m the one who woke up

But normally it is left out.

Because they are all in the past tense and all have the same subject: I.

Here are the three verbs:

• صحيت = I woke up
• غسلت = I washed
• شربت = I drank

That final -ت is the normal past ending for I in Egyptian Arabic.

This is a very useful pattern to learn:

• كتبت = I wrote
• سمعت = I heard
• فتحت = I opened

So the sentence is a straightforward sequence of past actions.

وشي means my face.

It is made of:

• وش = face
• -ي = my

So:

• وش = face
• وشي = my face

This -ي possessive ending is very common in Egyptian Arabic:

• بيتي = my house
• اسمي = my name
• أختي = my sister

Also, وش is the everyday Egyptian word here. In Modern Standard Arabic, learners often meet وجه for face, but in Egyptian everyday speech وش is very common.

Because this is Egyptian Arabic, not Modern Standard Arabic.

In Egyptian Arabic, the everyday word for water is:

• ميه or مية = mayya = water

In Modern Standard Arabic, you usually learn:

• ماء

So this sentence is using natural spoken Egyptian vocabulary.

That kind of difference is very common:

• spoken Egyptian uses everyday colloquial words
• MSA uses more formal/literary words

Because ميه is grammatically feminine, so the adjective has to agree with it.

• ميه باردة = cold water

Here:

• ميه = feminine noun
• باردة = feminine form of cold

Arabic adjectives agree with the nouns they describe in gender and number.

Compare:

• مَيّه باردة = cold water
• شاي بارد = cold tea

So باردة is there because ميه is feminine.

Because the phrase is indefinite: cold water / some cold water, not the cold water.

In Arabic, if a noun and adjective are indefinite, neither one takes ال:

• ميه باردة = cold water

If you wanted to say the cold water, you would say:

• الميه الباردة

So this sentence is talking about water in a general/indefinite sense, just like English often does in I drank cold water.

و means and.

So:

• غسلت وشي = I washed my face
• وشربت ميه باردة = and I drank cold water

In Arabic, especially in everyday speech, actions are often linked together very simply with و:

• روحت البيت وأكلت ونمت = I went home, ate, and slept

So the sentence is just a natural chain of actions:

1. I woke up
2. I washed my face
3. I drank cold water

Yes. All the verbs are in the past tense, and the sentence narrates a short sequence of completed actions.

• صحيت = woke up
• غسلت = washed
• شربت = drank

So the whole sentence sounds like a simple report of what happened, similar to English:

• When I woke up, I washed my face and drank cold water.

This is a very common storytelling pattern in Egyptian Arabic:

• لما + past verb, then more past verbs to continue the story.

The verbs here come from these basic forms:

• صحي / يصحى = to wake up
• غسل / يغسل = to wash
• شرب / يشرب = to drink

In the sentence, they appear in the past tense, first person singular:

• صحيت = I woke up
• غسلت = I washed
• شربت = I drank

Learning the base form plus the past I form is very helpful, because you will start noticing the same patterns across many verbs.
