Learn Arabic (Modern Standard): فاوض السفير الوفد في السفارة. - The ambassador negotiated with the delegation in the embassy.

The root of this verb is ف-و-ض (f-w-d). Form III verbs in the past tense follow the pattern فاعل (fā'ala). By inserting the long 'a' sound after the first root letter, we get فاوض (fāwaḍa), meaning 'he negotiated'.

The translation says 'negotiated with', but I do not see an Arabic word for 'with' (like مع). Why is that?

This is a very common feature of Form III verbs! The Form III pattern often builds the idea of 'doing an action with someone' directly into the verb itself. Because of this, the person or group you are interacting with becomes the direct object of the sentence. فاوض already means 'negotiated with', so الوفد (the delegation) just follows right after it as the direct object.

The words for 'ambassador' and 'embassy' look very similar. Do they come from the same root?

Yes! They both come from the root س-ف-ر (s-f-r), which has to do with traveling, journeying, or mediating. السفير (as-safīr) means the ambassador, while the pattern with the feminine ending gives us السفارة (as-safāra) for the embassy.

If I want to pronounce the full case endings at the ends of the words, what would they be here?
