قرأت الفاتورة في البيت، ثم وضعتها في الحقيبة مع البطاقة.

A careful MSA reading, if the subject is I, is:

qaraʾtu al-fātūrata fī al-bayti, thumma waḍaʿtuhā fī al-ḥaqībati maʿa al-biṭāqati.

If the subject is she, it would be:

qaraʾat al-fātūrata fī al-bayti, thumma waḍaʿat-hā fī al-ḥaqībati maʿa al-biṭāqati.

The normal Arabic spelling here does not show the short vowels, so both readings look the same in writing.

It can mean either one in unvoweled Arabic writing.

• قَرَأْتُ = I read
• قَرَأَتْ = she read

The same kind of ambiguity also appears in وضعتها:

• وَضَعْتُها = I put it
• وَضَعَتْها = she put it

So without vowel marks, you usually rely on context or the provided translation.

Because Arabic often attaches object pronouns directly to the verb.

So:

• وضعت = I put / she put
• ها = it / her for a feminine singular object

Together:

• وضعتها = I put it or she put it

This is very normal Arabic structure. English uses a separate word, but Arabic often uses a suffix.

-ها is a feminine singular object pronoun. Here it most naturally refers to الفاتورة.

So:

• الفاتورة is grammatically feminine
• therefore it becomes the feminine pronoun ها

Even though English says it, Arabic still has to choose a grammatical gender. Since الفاتورة is feminine, Arabic uses -ها, not -ه.

ثم means then and shows sequence.

It tells you that one action happened first, and the next action happened after that:

1. قرأْتُ/قرأَتْ الفاتورة
2. ثم وضعتُها/وضعتْها في الحقيبة

Compared with و (and), ثم makes the order clearer and often sounds a bit more step-by-step.

Literally, it means in the house, but in many contexts it is naturally translated as at home.

Arabic often uses في for general location, where English may choose either:

• in the house
• at home

So both are possible depending on the context and the most natural English wording.

Because ال is the Arabic definite article, meaning the.

So:

• الفاتورة = the invoice / the bill
• البيت = the house / home
• الحقيبة = the bag
• البطاقة = the card

In this sentence, all of these are treated as definite, specific things.

A pronunciation note: in all four words here, the ل of ال is pronounced, because ف, ب, and ح are moon letters.

It means with the card or together with the card.

• مع = with
• والبطاقة would be and the card

So the idea is that the invoice was put into the bag together with the card, not just added as another item in a list with and.

That ending is called tāʾ marbūṭa (ة). It very often marks feminine nouns.

In this sentence:

• الفاتورة
• الحقيبة
• البطاقة

are all feminine nouns.

In pause, ة is usually pronounced like -a or -ah:

• fātūra
• ḥaqība
• biṭāqa

But in full grammatical pronunciation, the t sound reappears before case endings, as in:

• الفاتورةَ = al-fātūrata
• الحقيبةِ = al-ḥaqībati

If the subject is I, a fully vocalized version is:

قَرَأْتُ الفاتورةَ في البيتِ، ثُمَّ وَضَعْتُها في الحقيبةِ معَ البطاقةِ.

Here is why the endings are what they are:

• الفاتورةَ is in the accusative because it is the direct object of قرأ
• البيتِ is genitive after في
• الحقيبةِ is genitive after في
• البطاقةِ is genitive after مع

If the subject is she, the verbs would instead be vocalized as:

قَرَأَتْ and وَضَعَتْها

In normal Arabic writing, these short vowels and case endings are usually not written.
