pheromone
Other forms: pheromones
Pheromones are chemical signals that animals send to each other. You can think of pheromones as an invisible form of communication.
Scientists suspect that humans secrete pheromones, which are sort of like hormones that are released outside the body, but there's still no proof that we can perceive them the way other animals can. Ants, for example, send complex messages using these chemicals, directing each other toward food or warning of danger. Other animals use pheromones to attract mates and mark territory. Pheromone, modeled on hormone, is from the Greek pherein, "to carry."
