West Syriac: Mor (as pronounced respectively in eastern and western dialects, from Syriac: ܡܪܝ or East Syriac: Mar, Mār(y), written with a silent final yodh) is a title of respect in Syriac, literally meaning 'my lord'. It is given to all saints and is also used before Christian name of bishops. The corresponding feminine form given to women saints is Mart or Mort (Syriac: ܡܪܬܝ, Mārt(y)). The title is placed before the Christian name, as in Mar Aprem/Mor Afrem (Ephrem the Syrian) and Mart/Mort Maryam (Mary, mother of Jesus).
The variant Maran or Moran (Syriac: ܡܪܢ, Māran), meaning "Our Lord", is a particular title given to Jesus, either alone or in combination with other names and titles. Likewise, Martan or Mortan (Syriac: ܡܪܬܢ, Mārtan, "Our Lady") is a title of Mary, mother of Jesus.
Occasionally, the term Maran or Moran has been used of various patriarchs and catholicoi. The Syriac Orthodox Patriarch of Antioch, the Malankara Orthodox Catholicos and the Syro-Malankara Major Archbishop Catholicos use the title Moran Mor. Sometimes the Indian bearers of this title are called Moran Mar, using a hybrid style from both Syriac dialects that reflects somewhat the history of Syrian Christians in Kerala. The Pope of Rome is referred to as Mar Papa by the Saint Thomas Christians of India.
