الهدية دي مش غالية، بس اختي هتحبها.

Yes—in English, this gift has the demonstrative first. In Egyptian Arabic, the common pattern is usually:

noun + demonstrative

So:

الهدية دي = this gift

A few common examples:

• البنت دي = this girl
• الولد ده = this boy
• العربية دي = this car

Here, دي is the feminine form of this, because هدية is a feminine noun.

Because هدية is grammatically feminine.

In Egyptian Arabic:

• ده = this (masculine)
• دي = this (feminine)

So:

• الكتاب ده = this book
• الهدية دي = this gift

Even though an object like a gift is not biologically female, the noun هدية is grammatically feminine, so it takes دي.

In Arabic, the present-tense verb to be is usually not stated.

So English:

• The gift is expensive

becomes Arabic:

• الهدية غالية

And the negative:

• The gift is not expensive
• الهدية مش غالية

This is completely normal. In the present tense, Arabic often just puts the subject and the description next to each other.

مش is the common Egyptian way to say not.

So:

• غالية = expensive
• مش غالية = not expensive

It is very commonly used to negate adjectives, nouns, and many other sentence types in Egyptian Arabic.

Examples:

• هو مش هنا = He’s not here
• أنا مش تعبان = I’m not tired
• دي مش مشكلة = This isn’t a problem

Because the adjective has to agree with the noun in gender.

Since هدية is feminine, the adjective is feminine too:

• masculine: غالي
• feminine: غالية

So:

• كتاب غالي = an expensive book
• هدية غالية = an expensive gift

In your sentence:

• الهدية دي مش غالية = This gift is not expensive

Here, بس means but.

So:

• الهدية دي مش غالية، بس اختي هتحبها = This gift isn’t expensive, but my sister will love it

A useful note: بس can also mean only / just in other contexts, depending on the sentence.

Examples:

• أنا تعبان، بس هاجي = I’m tired, but I’ll come.
• بس كده؟ = Is that all?/Only that?

In careful or standard spelling, you will often see:

أختي

But in informal Egyptian writing, especially in chats, subtitles, or casual text, people often leave off the hamza and write:

اختي

Both refer to the same word: my sister.

The -ي at the end means my, so:

• أخت / اخت = sister
• أختي / اختي = my sister

In Egyptian pronunciation, it is usually said like okhti.

Exactly—it is made of several parts:

ه + تحب + ها

1. ه- = future marker, like will / going to
2. تحب = she loves / she likes
3. ها = it / her (feminine object pronoun)

So:

هتحبها = she will love it

In this sentence, ها refers back to الهدية, which is a feminine noun, so the attached pronoun is feminine too.

In the Egyptian present/future verb system, تـ is used with several subjects, including she.

For the verb حب (to love / like), you get forms like:

• أنا بحب = I love
• إنتَ بتحب = you (masc.) love
• إنتِ بتحبي = you (fem.) love
• هي بتحب = she loves

So:

• هي بتحبها = she loves it
• هي هتحبها = she will love it

The تـ here is normal for she.

Yes, ها can mean her or it, depending on what it refers to.

Arabic object pronouns agree with grammatical gender. Since هدية is feminine, the pronoun used for it is feminine:

• هدية → ها

So:

• هتحبها = she will love it
  literally, she-will-love-her, but in English we translate it as it because the thing being referred to is a gift.

This is very common in Arabic: inanimate nouns can take masculine or feminine pronouns depending on their grammatical gender.

A natural Egyptian pronunciation would be close to:

el-hadeyya di mish ghālya, bas okhti hathebbaha

A few pronunciation notes:

• الهدية → often sounds like el-hadeyya
• دي → di
• مش → mish
• غالية → ghālya
• اختي → okhti
• هتحبها → hathebbaha

The h in هتحبها is the future marker, and the word flows together pretty smoothly in speech.

Yes. This sentence is clearly Egyptian Arabic, and very natural. A more formal or MSA-style version would be different.

For example, in more formal Arabic you might see:

• هذه الهدية ليست غالية، لكن أختي ستحبها.

But in everyday Egyptian, your sentence is much more natural:

• الهدية دي مش غالية، بس اختي هتحبها.

Some key colloquial features here are:

• دي for this
• مش for negation
• بس for but
• هـ for the future

Usually it can cover both ideas.

The Egyptian future prefix ه-/ح- often corresponds to English:

• will
• going to

So اختي هتحبها can mean:

• My sister will love it
• My sister is going to love it

The exact nuance depends on context, but in many everyday sentences there is no big difference.

Yes, but بس is the most natural everyday choice here.

Other possibilities exist, such as لكن, but that sounds more formal or bookish in many contexts.

So for spoken Egyptian:

• الهدية دي مش غالية، بس اختي هتحبها
  is very natural.

If you said:

• الهدية دي مش غالية، لكن اختي هتحبها people would understand you, but it may sound less conversational.

The sentence has two parts:

1. الهدية دي مش غالية

   • الهدية دي = this gift
   • مش غالية = not expensive

2. بس اختي هتحبها

   • بس = but
   • اختي = my sister
   • هتحبها = will love it

So the structure is roughly:

[this gift] + [not expensive] + but + [my sister] + [will love it]

This is a very common and natural Egyptian Arabic sentence pattern.
