بعدين شفت بنطلون اسود وجربته كمان، وكان مريح.

In Levantine Arabic, بنطلون is usually a singular masculine noun, even though in English we normally say pants or trousers in the plural.

So Arabic says:

• بنطلون اسود = black pants / a pair of black pants
• جربته = I tried it on

The attached pronoun ـه means it, not them, because Arabic is treating بنطلون as one item.

This is very normal and is one of the first things English speakers notice.

بعدين means then, after that, or later.

In this sentence, it connects this action to something that happened before:

• بعدين شفت... = Then I saw...

In Levantine, بعدين is extremely common in everyday speech for telling a sequence of events.

شفت is the normal past-tense Levantine form meaning I saw.

It comes from the verb يشوف / شاف = to see.

In Levantine past tense:

• شفت = I saw
• شفتَ / شفتي etc. = other forms depending on who is doing the action

The ت at the end is the past-tense marker for I.

So:

• شفت بنطلون اسود = I saw black pants

Yes, in more formal spelling, it is usually written أسود.

But in informal Levantine writing, people often drop the hamza in writing, especially in chat, texting, and casual sentences. So you may see:

• أسود
• اسود

Both refer to black.

This kind of informal spelling is very common in dialect writing and usually does not change the meaning.

Because it describes بنطلون, which is treated as masculine singular.

In Arabic, adjectives usually agree with the noun in gender and number.

So here:

• بنطلون = masculine singular
• اسود = masculine singular

That is why you do not get a feminine or plural adjective here.

جربته means I tried it or, in this context, I tried it on.

It breaks down like this:

• جربت = I tried
• ـه = it / him (masculine singular object pronoun)

So:

• جربت + ه = جربته

Because بنطلون is masculine singular, the pronoun is ـه.

In English we usually say try on for clothes, but in Arabic جرّب often works by itself when the context is clear.

In Arabic, the verb جرّب often already gives the idea of trying something, and with clothes it naturally means trying it on.

So:

• جربته can mean I tried it
• but with clothing, it usually means I tried it on

Arabic does not always need a separate equivalent of English on here.

كمان means also, too, or sometimes as well.

Here:

• وجربته كمان = and I tried it too / as well

It suggests this was not the first thing the speaker looked at or tried.

In Levantine, كمان is very common and flexible. You will hear it constantly in conversation.

وكان مريح means and it was comfortable.

It breaks down like this:

• و = and
• كان = was
• مريح = comfortable

The hidden subject of كان is still بنطلون.

Since بنطلون is masculine singular, the predicate adjective is also masculine singular:

• كان مريح = it was comfortable

If the noun were feminine, the form would change.

Because this is colloquial Levantine, not fully vocalized Modern Standard Arabic.

In dialect writing, case endings are normally not written or pronounced, so you get:

• مريح

not something like a fully inflected formal form.

That is completely normal in spoken Arabic and in informal written dialect.

Yes. بنطلون refers to the whole garment: pants, trousers, or a pair of pants.

Even though English uses a plural form, Arabic uses one singular noun for the whole item.

So this sentence is naturally understood as talking about one pair of pants, not one leg of it.

Yes, it sounds clearly colloquial and natural in Levantine-style everyday speech and writing.

A few clues are:

• بعدين is very common in speech
• informal spelling like اسود
• simple spoken-style structure
• no case endings
• a conversational flow with كمان

A more formal Standard Arabic version would likely be written differently, but this sentence sounds normal for casual Levantine Arabic.

A rough pronunciation would be:

ba3deen shift bantaloon aswad w jarrabto kaman, w kaan mree7

A few notes:

• شفت sounds like shift here
• جربته is roughly jarrabto or jarrabtu depending on the speaker
• مريح is often pronounced something like mree7

Pronunciation varies by region, but this is a useful rough guide.
