Questions & Answers about رقم الهاتف ثلاثة أربعة خمسة.
Why do the numbers three, four, and five all end with the marker ة (taa marbuuta) here?
When you read a string of digits out loud, like a phone number, or just count numbers on their own without counting a specific object, you use the form ending in ة. This is the standard bare or default counting form for numbers 3 to 10 in Arabic.
Why does only the word for phone have the prefix for the (ال) attached to it, but the English translation says The phone number?
This is the Arabic possession structure (Idafa). To say the phone number, Arabic literally says number of the phone. In this combination, the first word (رقم) never takes the prefix ال (the), but it is still understood as a specific, definite thing because it belongs to the second word (الهاتف), which does have ال.
Where is the word for is in this sentence?
Arabic does not use a present tense verb for to be (am, is, are). You just put the two parts of the sentence side by side. Here, رقم الهاتف (the phone number) is placed directly next to the numbers ثلاثة أربعة خمسة (three four five), and the word is is naturally understood.
Do I need to say and between the numbers when reading a phone number?
No. Just like in English, when reading a phone number, you simply list the bare digits one after another. You do not need to insert the Arabic word for and (و) between them.
