بعد ما رجعنا من المتحف، كنت مبسوط ومش زهقان.

In Egyptian Arabic, بعد ما is a very common way to say after when it is followed by a whole clause.

So:

• بعد المتحف = after the museum
• بعد ما رجعنا من المتحف = after we came back from the museum

Here, ما is part of the expression and does not need to be translated word-for-word. Learners often want to translate it literally, but it is better to treat بعد ما as one chunk meaning after + a verb clause.

رجعنا comes from the verb رجع = to return / come back.

The ending -نا means we.

So:

• رجع = he returned
• رجعنا = we returned / we came back

In Egyptian Arabic, past-tense verbs often include the subject inside the verb itself, so you do not need a separate word for we.

Because the two parts of the sentence have different subjects:

• بعد ما رجعنا من المتحف = after we came back from the museum
• كنت مبسوط ومش زهقان = I was happy and not bored

This is normal in both English and Arabic. A time clause can have one subject, and the main clause can have another.

كنت is the past form of to be.

So:

• مبسوط = happy / pleased
• زهقان = bored / fed up
• كنت مبسوط = I was happy
• كنت مش زهقان or more naturally here كنت مبسوط ومش زهقان = I was happy and not bored

Without كنت, the phrase would usually sound more like a present-time description:

• أنا مبسوط = I am happy

Because this sentence is talking about a past situation, كنت is the natural choice.

By itself, كنت can mean either:

• I was
• you were when talking to one male

So yes, كنت is ambiguous on its own.

Usually, context tells you which meaning is intended. If someone wants to make it completely clear, they can add the pronoun:

• أنا كنت = I was
• إنت كنت = you were

In your sentence, the meaning has already been given to the learner, so we understand it as I was.

In Egyptian Arabic, مش is the normal negator for adjectives, nouns, and similar non-verbal expressions.

So:

• مش زهقان = not bored
• مش تعبان = not tired
• مش مدرس = not a teacher

But ما...ش is typically used with verbs:

• ما رجعناش = we didn’t come back
• ما رحتش = I didn’t go

Since زهقان is an adjective/state word, مش is the correct and natural negation here.

They are masculine singular forms.

They agree with the person being described in كنت, not with رجعنا.

So if the speaker is male:

• كنت مبسوط ومش زهقان

If the speaker is female:

• كنت مبسوطة ومش زهقانة

This is important: even though the earlier clause has we returned, the adjectives describe the person in the main clause, not the whole group.

A female speaker would normally say:

بعد ما رجعنا من المتحف، كنت مبسوطة ومش زهقانة.

The changes are:

• مبسوط → مبسوطة
• زهقان → زهقانة

كنت itself does not change for I was. The gender shows up in the adjectives.

Often yes, but it can be a little broader than English bored.

زهقان can mean:

• bored
• fed up
• restless
• sick of what’s going on

So مش زهقان could mean not bored, but depending on context it may also suggest not fed up or not tired of it.

This is one of those common Egyptian words whose exact English translation depends on the situation.

مبسوط is extremely common in everyday Egyptian Arabic and often sounds more natural in casual speech.

Very roughly:

• مبسوط = happy, pleased, having a good time, enjoying oneself
• سعيد = happy, but often feels more formal or bookish in everyday Egyptian

So in a sentence about coming back from the museum and describing how someone felt, مبسوط is a very natural colloquial choice.

A helpful pronunciation guide is:

baʿd ma ragaʿna men el-matḥaf, kont mabsūṭ wi mish zahʔān

A few notes:

• ج in Egyptian is usually pronounced like g in go, so رجعنا sounds like ragaʿna
• و often sounds like wi before a consonant
• ق in many Egyptian pronunciations becomes a glottal stop, so زهقان sounds like zahʔān

You do not need to pronounce it exactly like this from day one, but this is close to common Cairene Egyptian speech.
