Questions & Answers about الفاتورة على هذه الورقة، لكنها تحتاج إلى توقيع أمي.
In Arabic, the present-tense to be is usually not written or spoken in simple sentences like this.
So:
الفاتورة على هذه الورقة
literally looks like
the invoice on this paper
but it means
The invoice is on this paper.
This is a very common Arabic pattern called a nominal sentence.
Because فاتورة ends in ـة (the tāʾ marbūṭa), which usually marks a feminine noun.
So even though an invoice is not biologically female, it is grammatically feminine in Arabic. That is why later in the sentence Arabic uses feminine agreement:
- لكنها = but it / literally but she/it
- تحتاج = it needs in the feminine singular form
Because ورقة is a feminine singular noun, so it takes the feminine singular demonstrative هذه.
- هذا = this (masculine)
- هذه = this (feminine)
So:
- هذا الكتاب = this book
- = this paper
