افتح بقك.

A common Egyptian pronunciation is roughly eftaḥ boʔʔak.

A few notes:

• You may also see it transliterated as iftaḥ buʔʔak. Different books write the vowels differently.
• ح is a strong, breathy h sound.
• ق in Egyptian Arabic is usually pronounced as a glottal stop ʔ, not like the formal Arabic q sound.

So the second word does not sound like buqak in everyday Egyptian speech.

It is made of two parts:

• بقّ = mouth in Egyptian Arabic
• -ك = your

So بقك means your mouth.

In normal Arabic writing, short vowels are usually not written, so the ending -ك is written the same even though it is pronounced differently depending on who you are talking to.

Because Arabic usually adds possessive pronouns directly onto the noun.

So instead of saying something like mouth your, Egyptian Arabic says one word:

• بقك = your mouth

This is a very common pattern:

• اسمك = your name
• كتابك = your book
• بيتك = your house

افتح is the imperative form of the verb فتح = to open.

So افتح means open!

In this sentence, it is a command addressed to one male. That is the default singular masculine command form.

To one woman, you would say:

افتحي بقك

The verb changes from افتح to افتحي.

Also, the final ك in بقك is still written the same way, but it is pronounced differently:

• to a man: -ak
• to a woman: -ik

So:

• افتح بقك = said to one male
• افتحي بقك = said to one female

To a group, you would normally say:

افتحوا بقكم

Here:

• افتحوا = open! said to a plural group
• بقكم = your mouth / mouths with plural your

So the sentence changes both in the verb and in the possessive ending.

This is Egyptian Arabic.

The clearest sign is بقّ for mouth, which is colloquial. In Modern Standard Arabic, you would normally say:

افتح فمك

So:

• افتح بقك = Egyptian, everyday speech
• افتح فمك = Standard Arabic / more formal

Because spelling and pronunciation do not always match exactly in dialect writing.

In Egyptian Arabic, ق is very often pronounced as a glottal stop ʔ. But many words are still written with ق because that is the conventional spelling.

So in بقك, the ق is usually pronounced like a catch in the throat, not like a strong q.

Because everyday Arabic writing usually leaves out:

• short vowels
• shadda unless needed for clarity

So افتح بقك is a normal unvowelled way to write it.

A more fully marked version would look something like:

اِفتح بُقّك

But in real life, people usually do not write all those marks, especially in dialect.

It can sound direct or blunt, because it is a straight command.

Whether it sounds rude depends a lot on context:

• fine from a dentist or doctor
• fine from a parent to a child
• possibly too sharp in polite conversation

If you want to soften it, you could say:

• ممكن تفتح بقك؟ = Could you open your mouth?
• افتح بقك لو سمحت = Open your mouth, please

It is a normal everyday Egyptian word, but it is more colloquial and a little less formal than فم.

So بقّ sounds natural in casual Egyptian speech, but it is not the word you would usually choose in formal Standard Arabic.

A good way to think of it is:

• بقّ = everyday spoken Egyptian
• فم = formal / Standard Arabic
