هي تشغل الغسالة، وتنشر الغسيل، وتطوي الملابس.

They are in the imperfect form, which is the form Arabic uses for the present and sometimes the future.

In this sentence, they most naturally mean a present-time action or a habit/routine, depending on context. So the sentence could describe:

• what she is doing now, or
• what she regularly does

Arabic does not always separate she does and she is doing as sharply as English does.

Because تـ is the imperfect prefix for third-person feminine singular here.

Since the subject is هي = she, the verbs agree with a feminine singular subject:

• هي تشغل
• هي تنشر
• هي تطوي

Compare:

• هو يشغل = he operates/turns on
• هي تشغل = she operates/turns on

So the تـ here is a grammar marker, not part of the meaning by itself.

هي is not strictly necessary.

Arabic often leaves out subject pronouns when the verb already makes the subject clear. So you could also say:

تشغل الغسالة، وتنشر الغسيل، وتطوي الملابس.

That still clearly means she because the verb forms are feminine singular.

Including هي can add:

• emphasis
• contrast
• clarity

So هي is possible and correct, but often optional.

Because و is the Arabic word for and, and it is written as a prefix attached to the following word.

So:

• وتنشر = and she hangs/spreads
• وتطوي = and she folds

This is completely normal in Arabic spelling. Many short words, especially conjunctions and prepositions, attach directly to the next word.

These three words are related, but they do not mean the same thing:

• الغسالة = the washing machine
• الغسيل = the laundry / the wash
• الملابس = the clothes / garments

A useful way to think of them is:

• الغسالة = the machine
• الغسيل = the laundry as a load or washing
• الملابس = clothes in general

So the sentence moves through different household actions:

• using the washing machine
• hanging or spreading the laundry
• folding the clothes

Because Arabic often uses the definite article الـ in places where English would also naturally say the.

Here, the sentence is talking about familiar, specific household things:

• the washing machine
• the laundry
• the clothes

Using الـ makes them definite:

• الغسالة
• الغسيل
• الملابس

If you removed الـ, the meaning would become more indefinite, like a washing machine or clothes/laundry in a less specific sense.

They are all direct objects of the verbs, so in fully vocalized MSA they are in the accusative case.

That would be:

• الغسالةَ
• الغسيلَ
• الملابسَ

In normal unvoweled writing, these endings are usually not shown, so you just see:

• الغسالة
• الغسيل
• الملابس

And in pause, speakers often do not pronounce the full case ending anyway.

Because this verb comes from طوى / يطوي, a weak verb.

The final ي in تطوي is part of the verb pattern, not a separate word and not a pronoun.

Compare:

• هو يطوي = he folds
• هي تطوي = she folds

So the final ي belongs to the verb itself.

It can mean either, depending on context.

The verb شغّل / يشغّل often has meanings like:

• to turn on
• to operate
• to run
• to make work

So تشغل الغسالة could mean:

• she turns on the washing machine
• she runs the washing machine
• she operates the washing machine

All of these are close in this context.

That is a very good question, because نشر has a broad basic meaning: to spread out.

From that basic idea, it can mean different things in different contexts:

• نشر خبراً = he published news
• نشر الثوب = he spread out the cloth
• نشر الغسيل = he hung out / spread out the laundry to dry

So with الغسيل, the natural meaning is to hang out the laundry or spread the laundry out to dry.

Yes.

This sentence begins with the subject pronoun هي, so it has a subject-first feel:

هي تشغل الغسالة...

That is perfectly normal.

But Arabic also very often starts with the verb, and since the verb already shows she, you could simply say:

تشغل الغسالة، وتنشر الغسيل، وتطوي الملابس.

Both are correct. Starting with هي gives a little more emphasis to she.

It can easily describe a sequence of actions.

Because the verbs are linked with و and listed one after another, the sentence can naturally suggest:

1. she turns on the washing machine,
2. hangs out the laundry,
3. folds the clothes

It can also simply list household tasks she does, without strongly emphasizing exact order. Context decides how sequential it feels.
