• Aliturgical — Non-liturgical, wherein the Holy Liturgy is not celebrated, or lacking a liturgical character. In Orthodox liturgical tradition, the term describes specific fast days during Lent or Good Friday when the celebration of the Divine Liturgy is strictly forbidden.
• Apodeipnon — A Christian liturgical service celebrated in the evening, after supper, in the Byzantine and Eastern Orthodox traditions, characterized by penitence, thanksgiving for the completed day, and prayers for protection before sleep; commonly known as Compline. This monastic or parochial liturgical rite varies in length, existing in distinct forms such as Small Compline, used daily, and Great Compline, specific to the Lenten season.
• Archistrategos — A solemn religious title granted in the Eastern Christian tradition to the Holy Archangels (especially to Archangel Michael), viewed as the leaders or glorious commanders of the angelic hosts and the spiritual defenders of the faithful in the fight against demonic forces. The term preserves the Slavic-Byzantine phonetic path and holds a strong liturgical weight, being frequently used in akathists, prayers, and official hagiographies.
