What is "kollel"

A kolel or kollel (, pl. כוללים, kollelim, a "gathering" or "collection" [of scholars]) is an institute for full-time, advanced study of the Talmud and rabbinic literature. Like a yeshiva, a kollel features shiurim (lectures) and learning sedarim (sessions); unlike a yeshiva, the student body of a kollel consists of married men for the most part. A Kollel generally pays a regular monthly stipend to its members.
