conventicle

Origin

From Late Middle English conventicle, conventicule (“a gathering, meeting (especially a secret or unlawful one); (derogatory) a church”), from Latin conventiculum (“assembly; meeting (or the place involved); association”), from conventus (“assembled, convened”) + -culum (suffix forming noun diminutives), perfect passive participle of conveniō (“to assemble, convene, meet together”), from con- (“together, with”) (ultimately from Proto-Indo-European *ḱóm (“along, at, next to, with”)) + veniō (“to approach, come”) (ultimately from Proto-Indo-European *gʷem- (“to step”) + *-yéti (suffix forming intransitive, imperfective verbs)).
