conglomerate

First attested in the second part of the 16th century; from Latin conglomerātus, perfect passive participle of conglomerō (“to pile into a heap, to roll together”) (see -ate (Etymology 1, 2 and 3)), from con- (prefix indicating a being or bringing together of several objects) (ultimately from Proto-Indo-European *ḱóm (“beside, by, near, with”)) + glomerāre (from glomerō (“to pile into a heap, to make into a ball, glomerate”), from glomus (“ball of thread; ball-shaped mass”), from Proto-Indo-European *gel- (“to form into a ball; ball”)).
