هو لازم ياخد الدوا بعد الغدا.

هو means he. Here it marks the subject clearly.

In Egyptian Arabic, لازم often behaves more like necessary / must than a normal fully conjugated verb, so speakers commonly say:

• هو لازم ياخد... = He has to take...

If the subject is already clear from context, هو can be omitted:

• لازم ياخد الدوا بعد الغدا

Keeping هو makes it clearer who you are talking about.

لازم means must, have to, or need to.

A very common Egyptian pattern is:

• subject + لازم + imperfect verb

So here:

• هو لازم ياخد = he has to take

A useful thing to remember is that لازم does not change for person:

• أنا لازم آخد = I have to take
• إنت لازم تاخد = you have to take
• هي لازم تاخد = she has to take

After لازم, Egyptian Arabic normally uses the bare imperfect verb, not the بـ form.

So:

• لازم ياخد = he has to take

But:

• بياخد usually means he takes or he is taking in a normal present or habitual sense

Compare:

• هو بياخد الدوا كل يوم = He takes the medicine every day
• هو لازم ياخد الدوا = He has to take the medicine

So the missing بـ is completely normal here.

Yes. ياخد is the Egyptian Arabic form of Standard Arabic يأخذ.

The verb is the same root, but the colloquial form is different in pronunciation and often in spelling. In Egyptian Arabic, this verb is commonly:

• past: خد = he took
• imperfect: ياخد = he takes / he should take / he has to take, depending on context

So if you know يأخذ from Standard Arabic, ياخد is its Egyptian equivalent.

A common pronunciation is:

howwa lāzem yākhod ed-dawa baʿd el-ghada

A few pronunciation notes:

• هو often sounds like howwa or huwwa
• خ in ياخد is like the ch in German Bach or Scottish loch
• ع in بعد is a deep Arabic sound with no exact English equivalent
• غ in الغدا is a throaty sound, often compared loosely to a French-style r

This is because of sun letters and moon letters.

• In الدوا, the next letter is د, which is a sun letter, so ال assimilates. It is pronounced more like ed-dawa
• In الغدا, the next letter is غ, which is a moon letter, so ال stays audible as el-, giving el-ghada

So even though both words are written with ال, they are pronounced differently.

الدوا means the medicine or the medication.

This is the normal Egyptian colloquial word. It corresponds to Standard Arabic الدواء.

So:

• دوا = medicine
• الدوا = the medicine

In everyday Egyptian speech, الدوا is extremely common.

In Egyptian Arabic, casual spelling often drops the hamza and uses a simpler written form.

So:

• Standard Arabic: الغداء
• Egyptian casual spelling: الغدا

They refer to the same word, and in Egyptian Arabic it is pronounced more like el-ghada.

This kind of simplified spelling is very common in texting, subtitles, and informal writing.

In Egyptian Arabic, الغدا means lunch.

That can confuse English speakers because meal terms do not always line up exactly across dialects and cultures.

In Egyptian Arabic:

• الفطار = breakfast
• الغدا = lunch
• العشا = dinner / supper

So in this sentence, بعد الغدا means after lunch.

Yes, you can.

Egyptian Arabic often drops subject pronouns when the meaning is already clear from context. So both are possible:

• هو لازم ياخد الدوا بعد الغدا
• لازم ياخد الدوا بعد الغدا

The version with هو is a little clearer or more explicit. The version without it is very natural if everyone already knows you are talking about him.

It can vary a little depending on tone and context.

لازم often means:

• must
• have to
• need to

In many everyday situations, English might translate it as either must or has to. It usually sounds fairly strong, but not always harsh. For medical advice like this sentence, has to take the medicine after lunch is a very natural interpretation.

Not necessarily. بعد الغدا usually just means after lunch.

If you want to make it clear that it should happen right away, Egyptian Arabic can add something like:

• بعد الغدا على طول = right after lunch

So the original sentence gives the general timing, but not always the idea of immediately.

Keep لازم the same, and change the pronoun and the verb form.

Examples:

• أنا لازم آخد الدوا بعد الغدا = I have to take the medicine after lunch
• إنت لازم تاخد الدوا بعد الغدا = You have to take the medicine after lunch
• هي لازم تاخد الدوا بعد الغدا = She has to take the medicine after lunch
• هم لازم ياخدوا الدوا بعد الغدا = They have to take the medicine after lunch

So the main thing that changes is the pronoun and the imperfect verb form.
