اذا بدك، اغسل الصحن وخلي الفوطة هون.

Here إذا بدك means something like if you want, if you'd like, or if you feel like it.

In this kind of everyday Levantine sentence, it often works more as a softener than as a strict logical condition. So it does not always feel like a strong English if. It can make the command sound less blunt.

So:

• إذا بدك، اغسل الصحن = If you want, wash the dish
• In natural English, the tone may be closer to Wash the dish, if you want or If you don't mind, wash the dish

بدك means you want or sometimes you need, depending on context.

It is made of:

• بدّ = want/need
• -ك = you (masculine singular)

So:

• بدي = I want
• بدك = you want (to a man)
• بدها = she wants
• بدنا = we want
• بدكم = you want (plural)

A learner should know that Levantine uses بدّ very often for wanting and needing.

Because this is informal writing.

In more careful or formal spelling, you would usually write:

• إذا

In casual texting or everyday typed Arabic, people often leave out hamzas, so:

• اذا is very common

Both represent the same word here.

A rough pronunciation is:

iza baddak, ighsil iṣ-ṣaḥan w khallī l-fūṭa hōn

A few notes:

• إذا → iza
• بدك → often baddak or biddak, depending on region
• اغسل → roughly ighsil
• الصحن → the l of ال merges into ṣ, so it sounds like iṣ-ṣaḥan
• خلي → khallī
• هون → hōn

Because they are imperatives: direct commands.

• اغسل = wash!
• خلي = leave / keep / put!

In Arabic, commands usually do not need an explicit subject pronoun, because the verb form already implies you.

So Arabic says:

• اغسل الصحن = Wash the dish not
• You wash the dish

In this sentence, اغسل is the masculine singular imperative, so it is addressed to one man.

If you were speaking to a woman, you would normally say:

• اغسلي

If you were speaking to more than one person:

• اغسلوا

So:

• to a man: إذا بدك، اغسل الصحن
• to a woman: إذا بدِّك، اغسلي الصحن
• to a group: إذا بدكم، اغسلوا الصحن

With خلي, the singular form is often written خلي in everyday spelling, and for a group you would say خلّوا.

Here خلي means leave, keep, or put and leave.

So:

• خلي الفوطة هون = Leave the towel here / Keep the towel here

This verb is very common in Levantine and can have several related meanings depending on context:

• let
• leave
• keep
• make someone do something in some structures

But in this sentence, the most natural meaning is leave/keep.

الصحن can mean plate or dish, depending on context.

In everyday speech, صحن is a very common word for a plate or dish used for food.

Also, note the definite article:

• صحن = a plate / dish
• الصحن = the plate / dish

Because ص is a sun letter.

In Arabic, when ال comes before a sun letter, the l sound assimilates into the next consonant. So:

• written: الصحن
• pronounced roughly: iṣ-ṣaḥan or eṣ-ṣaḥan

So the l is written, but not really pronounced as l here.

فوطة usually means towel, cloth, or sometimes rag, depending on context.

In a kitchen sentence like this, الفوطة is very likely:

• a dish towel
• a kitchen towel
• or a cleaning cloth

So the exact English word depends on the situation, but towel/cloth is the main idea.

هون means here.

It is the normal Levantine colloquial word for here.
The more formal / Standard Arabic word is:

• هنا

So:

• Levantine: هون
• Standard Arabic: هنا

Both mean here, but هون is what you expect in everyday spoken Levantine.

It sounds natural for everyday speech.

By itself, an imperative can sound direct, but إذا بدك softens it. So the whole sentence feels like a normal household instruction or request, not unusually rude.

Compare:

• اغسل الصحن وخلي الفوطة هون = more direct
• إذا بدك، اغسل الصحن وخلي الفوطة هون = softer, more casual, less sharp

So yes, this is a very normal Levantine way to say it.
