Questions & Answers about علينا أن نستخدم موارد متجددة مثل الشمس والرياح.

How does "علينا أن" express "we must"?
In Arabic, obligation is often expressed using the preposition على (on/upon) attached to a pronoun. So علينا literally means "upon us". When followed by أن (that/to) and a present tense verb like نستخدم (we use), the whole phrase creates the meaning "it is upon us that we use" or simply "we must use".
Why is the adjective "متجددة" (renewable) in the feminine singular form when "موارد" (resources) is plural?
This showcases a fundamental rule in Arabic: non-human plurals (like موارد) are treated as grammatically feminine singular. Therefore, any adjectives describing them must be in the feminine singular form, which is why متجددة ends with a taa marbuta (ة).
Both "موارد" and "متجددة" are the object of the verb. If I read this aloud with case endings, why wouldn't they rhyme perfectly?
Because they are the object of the verb, both are in the accusative case. However, موارد (resources) has a specific plural pattern that makes it a "diptote" (a word that refuses double vowels or tanween). It will end with a single fatha (مواردَ), while the adjective متجددة is a regular word and takes the standard double fatha (متجددةً).
The word "متجددة" looks a lot like "جديد" (new). How are they related?
They share the same three-letter root: ج - د - د (j-d-d). While جديد is a simple adjective meaning "new", متجددة is built from a more complex verb pattern (Form V) that indicates an ongoing or reflexive process. Literally, it means "renewing itself", which perfectly translates to "renewable" in the context of energy.
