Etymology
Origin of propagate
First recorded in 1560–70; from Latin propāgātus (past participle of propāgāre “to reproduce (a plant) by cuttings, spread for sprouting, propagate, enlarge),” equivalent to propāg(ēs) “something set out, scion, slip” ( pro- pro- 1 + pāg-, base of pangere “to fasten” + -ēs noun suffix) + -ātus -ate 1
Explanation
To propagate is to be fruitful and multiply, by the usual routes of reproduction, or by spreading something around — like a rumor. Propagate comes from the Latin word propagare, which means "to reproduce plants, breed." Plants love to propagate, especially when someone with a green thumb starts off with a jade plant stem in water and ends up with a garden full of the succulents. Plants aren't the only things to propagate like bunnies: in some apocalyptic movies, a virus propagates quickly, killing almost everyone in the world. Sound and light can also spread, or propagate, through the air.
