What does sparker mean?
A sparker is principally a person or device that produces sparks. It may refer to equipment used to ignite fuel, as in starting a fire or igniting an engine, and it can also denote a spark plug or a comparable ignition component. Less commonly, a sparker is someone who stimulates interest or initiates a movement among other people. The word is related to spark and therefore carries associations with energy, sudden illumination, and the moment that sets something in motion. In ordinary modern speech, however, it is more specialized and less common than spark itself. Its literal and figurative uses preserve the same basic idea: something relatively small that produces a visible or consequential effect.
A person or device that produces sparks, especially one used for ignition.
"The mechanic replaced the faulty sparker before starting the engine."
The term is relatively uncommon in general modern English and is more likely to occur in technical, historical, or specialist contexts.
A person who stimulates interest, activity, or enthusiasm in others.
"Her energetic speeches made her a sparker for the young movement."
This figurative sense is uncommon but idiomatic.
The regular plural of the literal sense is sparkers, referring to devices or people that produce sparks.
"The technicians tested each of the sparkers before fitting it to the engine."
A sparker turns a tiny flash of energy into ignition—and, figuratively, into the spark that sets people or events in motion.

The extended sense of one who stimulates or sets something in motion developed naturally from the idea of starting with a spark.
