هي بتدعك البقعة في القماش بالصابون.

In Egyptian Arabic, بـ on the verb usually marks the present / ongoing / habitual tense. So بتدعك can mean either:

• she is scrubbing
• she scrubs

The exact meaning depends on context. Egyptian Arabic often uses the same form for both a current action and a habitual one.

Yes, the sentence can work without هي. Arabic often drops subject pronouns because the verb already shows the person and gender. So بتدعك البقعة في القماش بالصابون is also fine.

Including هي can add clarity, emphasis, or contrast, like she in English when you want to make the subject explicit.

We know from هي, which means she, and from the verb form بتدعك, which matches a third-person feminine singular subject in Egyptian Arabic.

So the verb is agreeing with هي, not with البقعة.

البقعة is the object, not the subject.

The structure is:

• هي = subject
• بتدعك = verb
• البقعة = direct object
• في القماش = where the stain is
• بالصابون = the tool/material used

So she is doing the action, and the stain is what she is scrubbing.

Yes, and that is a very common learner question. In Egyptian Arabic, في is often used more broadly than English in. Depending on context, it can correspond to in, on, or sometimes just indicate location in a general way.

So البقعة في القماش is literally something like the stain in the cloth/fabric, but natural English may say on the cloth or from the cloth, depending on the situation.

Yes, but it changes the nuance.

• في القماش focuses on the stain’s location: it is in/on the fabric
• من القماش would focus more on removing the stain from the fabric

So the sentence as written describes the stain as being in the cloth, while من القماش would sound more removal-oriented.

بـ here means with or by means of. So بالصابون means with the soap or more naturally with soap.

In Arabic, short prepositions like بـ attach directly to the following word. So:

• بـ + الصابون becomes
• بالصابون

This is completely normal Arabic spelling.

Both are possible, but they are not exactly the same.

• بالصابون = with the soap / with soap in a specific or familiar sense
• بصابون = with soap, more indefinite

In real speech, Arabic often uses the definite article where English would just say soap in a general way. So بالصابون sounds very natural here.

Yes. In Egyptian Arabic, the بـ present form often covers both meanings. Without extra context, هي بتدعك البقعة في القماش بالصابون can mean either:

• She scrubs the stain with soap
• She is scrubbing the stain with soap

Context tells you which one is intended.

It is specifically Egyptian Arabic in its verb form, especially because of the بـ in بتدعك. That b- present marker is a major feature of Egyptian and other spoken dialects, not standard MSA usage.

A Modern Standard Arabic sentence would be built differently.

The word order is:

هي + بتدعك + البقعة + في القماش + بالصابون

That is:

• subject
• verb
• object
• location phrase
• instrument phrase

This is a very normal spoken Arabic structure. You may also hear slight reordering in conversation, but this version is straightforward and natural.
