Correct spelling for the English word "caire" is [kˈe͡ə], [kˈeə], [k_ˈeə] (IPA phonetic alphabet).
The word "caire" is derived from the Arabic word "Al-Qāhirah", which means "The Victorious". This name refers to the city of Cairo, the capital of Egypt. The English word "Cairo" is a modified version of "caire". The Arabic name "Al-Qāhirah" was given to the city in the 10th century, after it was conquered by the Muslim Fatimid dynasty. The name was chosen to symbolize the Fatimids' victory over their rivals. Over time, the name Caire/Cairo became widely used in the English language to refer to the city of Cairo.
