Etymology
Origin of relay
First recorded in 1375–1425; (for the verb) late Middle English relaien “to unleash fresh hounds in a hunt,” from Middle French relaier, Old French: “to leave behind, release,” from re- re- + laier “to leave” (dialectal variant of laissier, from Latin laxāre; see relax); (for the noun) late Middle English relai “set of fresh hounds,” from Middle French, derivative of relaier
Explanation
If you relay something, you pass it to another person. When you relay the information that your pet monkey is known to attack people to your neighbors, you should bring a basket of muffins. Relay comes from the French relayer, which means "to change hounds on a hunt." It still has that sense of something passed in motion. You might run a relay race — each team member carries a baton part-way, then passes it on. We relay news, as when you take a message from Sally and relay it to Harry. A fresh work crew is a relay, and so is an electrical switch that can turn a second circuit on.
