Etymology: "Rodenticides" is simply the plural of "rodenticide," and the word is built from three parts: "rodent," a "-i-" linking vowel, and "-cide." The first part comes from Latin "rodere," meaning "to gnaw," which is why rodents are named for their habit of chewing through things. The ending traces back to Latin "caedere," "to cut, strike, kill," which passed into Middle French as "-cide" and then into English, where it became a standard way to name agents that kill a particular kind of creature or thing. That ending is the key to the whole family of words. English uses "-cide" in forms like "insecticide," "herbicide," and "pesticide," each pairing the suffix with a different target. "Rodenticide" follows the same pattern, with the "-i-" connecting the stem "rodent" to the suffix, as it does in several other coinages built this way.
