Questions & Answers about يجب علينا أن ننتبه في السيرك.
Why does the sentence use علينا after يجب? Doesn't Arabic have a normal verb for "we must"?
In Arabic, obligation is often expressed using an impersonal verb that doesn't change forms to match the subject. يجب literally means "it is necessary". To specify who must do the action, you use the preposition على (upon) plus an attached pronoun. Here, على + ـنا (us) becomes علينا. So, يجب علينا literally translates to "It is necessary upon us".
If you read this out loud, why does ننتبه end with an "a" sound (fat-ha) instead of the usual "u" sound (damma)?
This is because of the word أن (to/that) right before it. أن triggers what is called the subjunctive mood in the following present-tense verb. For most regular verbs, this means changing the final vowel from a "u" (damma) to an "a" (fat-ha). So instead of "nantabihu", we say أن ننتبهَ (an nantabiha).
How can I tell that ننتبه means "we" pay attention?
In the present tense, verbs starting with the prefix نـ (noon) indicate "we". The base verb here is انتبه (to pay attention), and adding the نـ prefix at the beginning makes it ننتبه (we pay attention).
السيرك looks and sounds a lot like "circus". Is it a borrowed word?
