Have you heard about the new study on pheromonal attraction?

Yeah, I read something about that; it's fascinating how it works!

Root Explanation

Pheromonal → It is formed from "pheromone" (from Greek "pherein", meaning to carry or transmit, and "hormon", meaning to excite or stimulate) and the suffix "-al" (meaning pertaining to). The word "pheromonal" refers to something that pertains to pheromones, which are chemical signals that carry information between individuals of the same species.

Memory Tip

Think of 'carrying' ('pherein') a signal that 'excites' ('hormon') others — that's why 'pheromonal' relates to the chemicals that influence behavior.
