ʿAbd (Arabic: عبد) is an Arabic word meaning one who is subordinated as a slave or a servant, and it means also to worship. The word can also be transliterated into English as 'Abd, where the apostrophe indicates the ayin, denoting a voiced pharyngeal fricative consonant or some reflex of it. In Western ears, it may be perceived as a guttural 'a' sound.
It appears in many common Arab names followed by Al (the) in form of "Abd ul", "Abd ul-", etc.; this is also commonly transliterated as "el-," in the form "Abd el-", meaning "servant of the-". This is always followed by one of the names for God. These names are given in List of Arabic theophoric names and 99 Names of God.
