ما كان لازم تتركي الصحون بالمطبخ.

It is a very common Levantine pattern meaning something like:

• it wasn’t necessary to...
• you shouldn’t have...

Literally:

• ما = not
• كان = was
• لازم = necessary / required / supposed to

So ما كان لازم تتركي... is literally it wasn’t necessary that you leave..., but in everyday English the natural meaning is often you shouldn’t have left...

كان puts the idea into the past.

Compare:

• ما لازم تتركي الصحون بالمطبخ = you shouldn’t leave the dishes in the kitchen / don’t leave the dishes in the kitchen
• ما كان لازم تتركي الصحون بالمطبخ = you shouldn’t have left the dishes in the kitchen

So كان is what gives the sentence the past, regret/criticism type meaning.

Because after expressions like لازم in Levantine, Arabic normally uses the imperfect verb, not the simple past.

So:

• لازم تتركي = you should leave
• كان لازم تتركي = you should have left
• ما كان لازم تتركي = you shouldn’t have left

Even though the overall meaning is about the past, the verb after لازم stays in the imperfect form. The past meaning comes from كان.

In Levantine, the prefix بـ often marks the ordinary present/habitual indicative, but it is usually dropped after modal words like لازم.

So you say:

• لازم تروحي = you have to go
• not usually لازم بتروحي

Likewise here:

• ما كان لازم تتركي is correct and natural
• ما كان لازم بتتركي would sound wrong or very unnatural in this structure

تتركي is addressing one female.

The ending -ي here shows feminine singular in Levantine.

Related forms:

• تترك = you leave, to one male
• تتركي = you leave, to one female
• تتركوا = you leave, to a group

So this sentence is specifically said to a woman or girl.

You would say:

ما كان لازم تترك الصحون بالمطبخ.

If you were speaking to a group, you could say:

ما كان لازم تتركوا الصحون بالمطبخ.

So the rest of the sentence stays the same; only the verb changes to match the person being addressed.

الصحون means the dishes or the plates, depending on context.

Singular:

• صحن = plate / dish

Plural:

• صحون = plates / dishes

In everyday Levantine, الصحون is a very normal word for dishes in a kitchen context.

A pronunciation note: because ص is a sun letter, الصحون is pronounced more like aṣ-ṣuḥūn, not al-saḥūn.

بالمطبخ means in the kitchen.

It is made of:

• بـ = in / at
• الـ = the
• مطبخ = kitchen

So:

• بالمطبخ = in the kitchen

In Levantine, بـ is very commonly used for location, where English would use in or at.

Yes, but بالمطبخ is often the more natural colloquial choice in Levantine for this kind of sentence.

So both can make sense, but:

• بالمطبخ = very natural in spoken Levantine
• في المطبخ = possible, but sometimes sounds a bit more formal or less typically colloquial depending on the speaker and region

For a learner aiming at everyday Levantine, بالمطبخ is a good form to use.

Grammatically, the literal idea is it wasn’t necessary. But in real conversation, ما كان لازم very often carries criticism and is best understood as:

you shouldn’t have...

So in this sentence, the most natural interpretation is:

• you shouldn’t have left the dishes in the kitchen

In the right context, it could be understood more literally as there was no need to leave the dishes in the kitchen, but that is usually not the main feeling.

That is the most neutral word order here:

• verb: تتركي
• object: الصحون
• place: بالمطبخ

So the sentence flows as:

leave + the dishes + in the kitchen

This is very natural in Arabic. You can sometimes move parts around for emphasis, but this order is the basic, straightforward one.

A careful Levantine-style pronunciation would be roughly:

ma kān lāzem titrki ṣ-ṣḥūn bil-maṭbakh

A few helpful notes:

• ما كان → ma kān
• لازم → lāzem
• تتركي is often said quickly, something like titrki
• الصحون has assimilation, so the l of الـ disappears in pronunciation: ṣ-ṣḥūn
• بالمطبخ sounds like bil-maṭbakh

You do not need to pronounce every written vowel very strongly; spoken Levantine often compresses them.

It can cover all of those depending on context.

لازم is very flexible. It can mean:

• must
• need to
• have to
• should
• supposed to

In ما كان لازم تتركي..., the best English match is usually shouldn’t have.

So you should not think of لازم as matching only one English word every time. Its exact force depends on the sentence and context.
