Questions & Answers about التذكرة عشرون دولارا.
Why is the word for "dollars" singular (دولارا) instead of plural?
In Arabic, numbers from 11 to 99 are followed by a singular noun. It might feel strange to an English speaker, but you literally say "twenty dollar".
What is the purpose of the alif (ا) at the end of دولارا?
It holds the double fatHa ending (pronounced "-an"), which marks the accusative case. Nouns counted by numbers 11 to 99 must be singular, indefinite, and accusative. For most words, that accusative ending means adding an extra alif to the spelling.
التذكرة (the ticket) is feminine, but دولار (dollar) is masculine. Does عشرون (twenty) need to match either of them in gender?
No, the numbers for the "tens" (20, 30, 40, up to 90) have only one form. You use عشرون whether you are counting masculine things or feminine things!
Why isn't there an Arabic word for "is" here?
Arabic doesn't use a verb for "to be" in basic present-tense sentences like this. Putting a definite subject التذكرة (The ticket) right before the information about it automatically means "The ticket is twenty dollars."
