Ectenia
An ektenia (from Greek ἐκτένεια (ekténia), from Greek ἐκτενής (ektenés) 'diligence'), often called by the better known English word litany, consists of a series of petitions occurring in the Eastern Orthodox and Byzantine Catholic liturgies. In Greek, συναπτή, synaptê is the prevalent ecclesiastical word for this kind of litany, while in Church Slavonic, ектенїѧ, yekteniya is the preferred word.
