Questions & Answers about سوف نزرع خمس عشرة شجرة في الدفيئة الجديدة.
Why is the number fifteen written as خمس عشرة with a masculine first part and a feminine second part?
This is the reverse gender agreement rule for numbers 13 to 19. The counted noun, شجرة (tree), is feminine. In these compound numbers, the unit part (3 to 9) takes the opposite gender of the noun, making خمس masculine. However, the ten part matches the noun's gender, making عشرة feminine.
Why is the word for trees (شجرة) singular instead of plural here?
In Arabic, numbers from 11 to 99 must be followed by a singular, indefinite noun. This noun is also always in the accusative case. So instead of using a plural form, we use the singular شجرة.
Why do both parts of the number خمس عشرة have fixed endings?
Compound numbers from 11 to 19 (except for the number 12) are indeclinable. This means their endings are permanently frozen. Both parts will always end in a fatha (the -a sound) regardless of their grammatical role in the sentence.
Why does the adjective الجديدة (the new) have ال (al-) attached to it?
Adjectives must strictly match the noun they describe. Because the noun الدفيئة (the greenhouse) is definite and starts with ال, the adjective describing it must also be definite, which gives us الجديدة.
