فرشاية السنان تبعك يمكن تكون جنب معجون السنان.

Yes. فرشاية السنان is a very normal Levantine way to say toothbrush.

A literal breakdown is:

• فرشاية = brush
• السنان = the teeth

So literally it is the brush of the teeth, but in natural English that is just toothbrush.

A learner may also know فرشاة الأسنان from Modern Standard Arabic. In Levantine, فرشاية السنان sounds more colloquial and natural.

Because السنان is the common colloquial Levantine form, while الأسنان is the more formal/Standard Arabic form.

So:

• السنان = teeth in everyday Levantine
• الأسنان = teeth in MSA / formal Arabic

This kind of shortening or sound change is very common in dialects.

تبعك means yours or belonging to you.

In Levantine, تبع is often used to show possession, especially in everyday speech:

• تبعك = yours
• تبعي = mine
• تبعه = his
• تبعها = hers

So:

• فرشاية السنان تبعك = your toothbrush

This is a very common colloquial structure.

Because Levantine often uses تبع + pronoun to express possession in a very natural spoken way.

So instead of forming possession directly on the noun, speakers often say:

• الكتاب تبعي = my book
• السيارة تبعها = her car
• فرشاية السنان تبعك = your toothbrush

You may also hear other ways to express possession, but تبعك is extremely common in speech and feels very natural.

يمكن here means maybe, might, or could.

So the sentence is expressing possibility:

• يمكن تكون... = it might be... / maybe it is...

In Levantine, يمكن is very common for uncertainty or guessing.

Examples:

• يمكن يجي بكرا = He might come tomorrow.
• يمكن يكون بالبيت = He might be at home.

Because the subject is feminine: فرشاية.

In Arabic, verbs agree with the grammatical gender of the subject.

• فرشاية is feminine
• so the verb is تكون = it is / it might be for a feminine subject

If the subject were masculine, you would usually get يكون instead.

So here:

• فرشاية السنان = feminine
• therefore تكون

Yes. Arabic often leaves the subject pronoun unstated when the verb already shows it.

Here, تكون already implies she/it for a feminine singular subject.

So the full idea is something like:

• فرشاية السنان تبعك يمكن هي تكون جنب معجون السنان

But Arabic normally does not need the separate هي here. The verb already carries that information.

جنب means next to, beside, or by.

In this sentence:

• جنب معجون السنان = next to the toothpaste

English learners sometimes expect an extra preposition because English says next to. But in Arabic, جنب itself already does that job.

Other common Levantine words with a similar meaning include:

• حد = beside / next to
• قرب = near

Because معجون السنان is the everyday Levantine expression for toothpaste.

Breakdown:

• معجون = paste
• السنان = teeth

So literally: teeth paste, which matches how many languages build the word toothpaste.

In formal Arabic, you would more often see معجون الأسنان, but in Levantine معجون السنان is very natural.

The sentence is structured like this:

• فرشاية السنان تبعك = your toothbrush
• يمكن = might / maybe
• تكون = be
• جنب معجون السنان = next to the toothpaste

So the order is roughly:

Your toothbrush + might be + next to the toothpaste

That is actually quite close to English in this example, even though the internal noun phrases are built differently.

It is specifically colloquial Levantine.

The clues are:

• فرشاية instead of more formal فرشاة
• السنان instead of الأسنان
• تبعك as a colloquial possession marker
• the overall spoken style

A more formal Standard Arabic version would be something like:

فُرشاةُ أسنانِك قد تكون بجانب معجون الأسنان or فُرشاة الأسنان الخاصة بك قد تكون بجانب معجون الأسنان

But for everyday Levantine conversation, the original sentence sounds much more natural.

A rough pronunciation guide would be:

farshaayet is-sneen tabaʕak yimkin tkuun janb maʕjuun is-sneen

A few notes:

• السنان is often pronounced more like sneen / snān depending on region and speed.
• تبعك contains the sound ع, which does not exist in English.
• يمكن may sound like yimkin in speech.

Pronunciation varies across Levantine regions, but this gives you a useful approximate sound.

Yes, very often you can.

For example:

• فرشاية السنان تبعك ممكن تكون جنب معجون السنان

This also means Your toothbrush might be next to the toothpaste.

In many everyday contexts, يمكن and ممكن overlap in meaning. The exact feel can vary a bit by region and speaker, but both are very common for possibility.
