Questions & Answers about هذا النادل له حساب واحد.
Why does the word for "one" (واحد) come after the word for "bill" (حساب)?
In Arabic, the numbers 1 and 2 act like adjectives. Just like other adjectives in Arabic, they come after the noun they describe. So instead of saying "one bill", you literally say "bill one" (حساب واحد).
How do we know to use واحد instead of the feminine form واحدة?
Because numbers 1 and 2 act like adjectives, they must match the gender of the noun they describe. The word for bill (حساب) is a masculine noun, so we must use the masculine word for one (واحد).
How does له translate to "has"?
Arabic doesn't have a direct verb for "to have". Instead, it uses prepositions with attached pronouns. له is made of the preposition لـ (to/for) and the pronoun suffix ـه (him/his). Literally, the sentence says "This waiter, to him [is] one bill."
Why does "This waiter" have the word "the" (الـ) in هذا النادل?
When you want to say "This [noun]", the noun must have "the" (الـ) attached to it. If you left it off and just said هذا نادل, it would change the meaning to a complete sentence: "This is a waiter." Adding الـ glues "this" and "waiter" together into a single phrase.
