Culture of Egypt
Arabic is Egypt's official language, it came to Egypt in the 7th century, and the Egyptian Arabic dialect today has become the modern speech of the country. Of the many varieties of Arabic, it is the most widely spoken second dialect, due to the influence of Egyptian cinema and media throughout the Arabic-speaking world. Egypt's position in the heart of the Arab world has also had reversed influence, adopting many words, phrases, and proverbs from neighboring Arabic speaking areas such as the Maghreb area and the Mashriq. Today the daily Egyptian Arabic adopted several French, Italian, Greek, Turkish, Armenian and English words to its dictionary, as well as keeping several other words from its own ancient languages such as Coptic and Demotic.
