ضروري ما نختار درجة حرارة عالية للملابس الحساسة.

Here ضروري means necessary, important, or a must. In Levantine, it often gives the sense of must or need to.

So ضروري ما نختار... means something like we must not choose... or it’s important not to choose....

A very common similar word in Levantine is لازم.

In Levantine Arabic, the usual way to negate a present/future verb is ما + verb.

So:

• ما نختار = we do not choose / we shouldn’t choose

By contrast, لا نختار sounds more like Standard Arabic or formal written Arabic.

نختار literally means we choose.

In Arabic, especially in instructions or general advice, the we form is often used in a broad, general way, similar to English sentences like:

• We don’t use high heat for this
• We add the salt at the end

It does not always mean a specific group of people. It can mean we in general, one, or even a soft kind of you.

If you were speaking directly to one person, you could also say ما تختار.

In everyday Levantine, a word like ضروري is often followed directly by a full clause, without أن.

So ضروري ما نختار... is normal colloquial structure.

In more formal Arabic, learners sometimes expect an extra linking word, but colloquial Levantine often leaves it out.

درجة حرارة literally means degree of heat, which is the normal Arabic expression for temperature.

This is an iḍāfa structure, meaning two nouns joined together:

• درجة = degree
• حرارة = heat

Together: temperature

Because درجة حرارة is treated as a feminine singular noun phrase, and the adjective has to agree with it.

So:

• درجة حرارة عالية = a high temperature

The adjective comes after the noun in Arabic, and here it is feminine singular:

• عالية = high, feminine
• عالي = high, masculine

للملابس is just:

• لـ = for
• الملابس = the clothes

When لـ joins ال, it becomes للـ.

So للملابس literally means for the clothes.

But Arabic often uses the where English would not. So للملابس الحساسة can still mean for delicate clothes in a general sense, not necessarily one specific set of clothes.

This is a very common Arabic pattern. With non-human plurals, Arabic often uses a feminine singular adjective.

So:

• الملابس = clothes, plural
• الحساسة = delicate/sensitive, feminine singular

Together: delicate clothes

In grammar books, this is often called deflected agreement. It is especially common in Standard Arabic, and it is also very common in Levantine usage.

الملابس is perfectly understandable, but it sounds a bit more standard or formal.

In everyday Levantine, many speakers would more naturally say things like:

• تياب
• هدوم (in some areas)

So a more casual spoken version might use تياب instead of ملابس.

It is understandable and natural enough, but it feels a little mixed in register.

Why?

• ضروري sounds very normal in speech
• الملابس is a bit more standard/formal
• درجة حرارة is also a fairly standard expression

So the sentence is not wrong, but it sounds a bit more neutral or semi-formal than very casual everyday Levantine.

A more everyday version could be:

• ما لازم نختار حرارة عالية للتياب الحساسة

This sounds more conversational because:

• ما لازم is a very common way to say shouldn’t / mustn’t
• حرارة عالية is simpler than درجة حرارة عالية
• تياب is more colloquial than ملابس

So the original sentence is fine, but this alternative may sound more natural in everyday Levantine speech.
