What does propagator mean?
A propagator is a person, organism, or thing that spreads, reproduces, or otherwise extends something. The word is especially common in biology and horticulture, where a propagator may be a plant, cutting, or piece of equipment used to produce new organisms. In general contexts, the noun can denote anyone who transmits ideas, customs, rumors, or practices. As a verb, propagate has two closely related uses: to make something spread widely, as in propagating an idea, and to reproduce or multiply, as when a species or plant propagates itself. The term is usually neutral in tone, although descriptions such as “propagator of disease” or “propagator of misinformation” carry an explicitly negative connotation. Its usefulness lies in connecting literal biological reproduction with the broader social process by which information, behaviors, and cultural practices pass from one person or group to another.
A person, organism, or thing that causes something to spread, reproduce, or increase.

In biology and horticulture, the term is common. For a person, it often has a formal or institutional tone.

The standard plural of the noun is “propagators.”
"The laboratory is testing several effective propagators for the endangered orchid."
A propagator can spread an idea, a disease, or even an entire species: the word celebrates multiplication in every sense.

Where does propagator come from?
The word comes from Latin propagator, an agent noun formed from propagare, meaning to extend or reproduce. Propagare was based on propago, a shoot or offshoot that could be planted to reproduce a plant. Through French and English usage, the word's range broadened from biological reproduction to the spreading of information and other intangible things. Modern cognates include propagate, propagation, and propaganda, although propaganda developed distinct political associations.
