Seminary is a type of educational institution.
Often a diocese might be attached to or affiliated with a larger Catholic college or university so that the larger college and its faculty provides more general education in history or theology while the seminary focuses on topics specific to the needs of future priests, such as training in canon law, the sacraments, and preaching, or specific to the particular order or diocese
 The English word is taken from the Latin seminarium, translated as seed-bed, an image taken from the Council of Trent document Cum adolescentium aetas which called for the first modern seminaries
