Question 1

Why do موردا (mawridan) and متجددا (mutajaddidan) end with an 'alif' when they mean 'a renewable resource'?

Accepted Answer

This is because they are the predicate of ليس (laysa, meaning 'is not'). Just like the verb 'to be' in the past tense (كان), ليس changes its predicate into the accusative case. In writing, this is shown by adding the 'alif' with the double fatha ending (tanwin) on both the noun موردا and its matching adjective متجددا.

Question 2

What is the exact role of بل (bal) here, and could I use لكن (lakin) instead?

Accepted Answer

بل means 'rather' or 'instead'. It is used specifically to correct or contradict the first part of the sentence, especially after a negative statement. While لكن (but) could technically work to show contrast, بل is the most natural choice here because it perfectly expresses 'it is not X, but rather Y'.

Question 3

How is the word متجددا (mutajaddidan) formed?

Accepted Answer

It is the active participle of a Form V verb, تجدد (tajaddada), which means 'to be renewed' or 'to renew itself'. By adding a 'mu-' prefix to the root, we get the adjective متجدد (mutajaddid), meaning 'renewable' or 'self-renewing'. The accusative case adds the final 'alif'.

Question 4

Is the verb ينفد (yanfadu) related to the word for window (نافذة)?

Accepted Answer

No, but they look very similar! The verb here is ينفد (with a 'daal' at the end), which means 'to run out' or 'to be depleted'. The word for window comes from a different root ending in 'dhaal' (ن ف ذ) meaning 'to pass through' or 'to penetrate'. This is a common reading trap for learners.
