Did You Know?

The origins of propagate are firmly rooted in the field of horticulture. The word was borrowed into English in the late 16th century from Latin propagatus, the past participle of the verb propagare, which means "to set (onto a plant) a small shoot or twig cut for planting or grafting." Propagare, in turn, derives from propages, meaning "layer (of a plant), slip, offspring." It makes sense, therefore, that the earliest uses of propagate referred to facilitating the reproduction of a plant or animal. Nowadays, however, the meaning of propagate can extend to the "reproduction" of something intangible, such as an idea or belief. Incidentally, propaganda also comes to us from propagare, although it took a somewhat different route into English.
