The word "受到" is formed by combining two characters: "受" (shòu), which means to receive or to undergo, and "到" (dào), which means to arrive or to reach. Their combination creates a single verb where "到" acts as a complement to "受", intensifying and completing its meaning. Conceptually, it merges the idea of "receiving" with the sense of that reception "arriving" or "taking effect", thus forming a unified notion of experiencing or incurring something, typically an action, feeling, or influence from an external source.
