The following list consists of concepts that are derived from both Christianity and Arab tradition, which are expressed as words and phrases in the Arabic language. These terms are included as transliterations, often accompanied by the original Arabic-alphabet orthography. Although Islam is the dominant religion among Arabs, there are a significant number of Arab Christians in regions that were formerly Christian, such as much of the Byzantine empire's lands in the Middle East, so that there are nearly fourteen million Arab Christians living around the world. Christianity has existed in the Arab world since the 1st century. Readers should also note that Arabic is written with the Arabic alphabet, and that different individuals and Christian groups may transliterate certain Arabic words into the Latin alphabet in various ways.
