هي قالت اهلا.

A natural Egyptian-style pronunciation is heyya 'aalet ahlan.

A rough breakdown:

• هي → heyya
• قالت → 'aalet
• اهلا → ahlan

The start of قالت has a small catch in the throat, like the sound in the middle of uh-oh.
You may also hear hiya for هي, especially in slower or more formal speech.

هي is the independent pronoun she.

So the sentence begins by explicitly naming the subject: she. In Arabic, this kind of pronoun can be used just like English she, but Arabic often does not need it because the verb already tells you who the subject is.

Because the subject is feminine: she.

• قال = he said
• قالت = she said

The final -ت is the past-tense marker for third person feminine singular. So the verb itself already shows that the subject is she.

Yes. قالت اهلا is a complete and natural sentence.

Arabic often drops subject pronouns when the verb already makes the subject clear. Since قالت already means she said, هي is optional here.

Including هي can still be useful when:

• you want to be extra clear about who did it
• you are contrasting her with someone else
• you want a slightly more explicit sentence

Yes. In Egyptian Arabic, subject + verb is very common, especially when the subject is a pronoun like هو or هي.

So هي قالت sounds very normal.

You can also have verb-first order in Arabic, but in everyday Egyptian, starting with the subject is often the more natural choice.

Here, اهلا is a greeting, so it works like hello or hi.

Depending on context, it can also carry a sense of welcome. A very common longer expression is أهلا وسهلا.

So in this sentence, اهلا is simply the word she said as a greeting.

In careful standard spelling, it is usually written أهلا with a hamza.

In informal writing, texting, and casual online Egyptian Arabic, people very often leave the hamza off and write اهلا instead. Both are easily understood.

So:

• أهلا = more careful spelling
• اهلا = very common casual spelling

Because Arabic can place the spoken words directly after said, just like English can in she said hello.

You do not need an extra word here. The structure is simply:

• هي = she
• قالت = said
• اهلا = hello

So the sentence works naturally without anything in between.

Arabic often leaves out quotation marks in short, simple sentences like this, especially in informal writing.

So هي قالت اهلا is perfectly normal.

If someone wanted to make the speech feel more clearly quoted, they might write something like:

• هي قالت: أهلا

But quotation marks or a colon are not required.

By itself, قالت most directly means said.

If Arabic wants to express told someone, it usually adds the person:

• قالت له = she said to him / she told him
• قالت لها = she said to her / she told her

In هي قالت اهلا, the meaning is clearly she said hello.

Other Arabic speakers would understand it easily.

The words هي and قالت are not only Egyptian; they also exist in Standard Arabic. What makes the sentence feel especially natural for everyday Egyptian use is the simple casual style and the likely pronunciation.

So this sentence is:

• very easy for Egyptians
• understandable across the Arabic-speaking world
• close to both colloquial and standard grammar in this particular case
