Etymology: The plural here is simple: "sterilisers" is just the regular plural of "steriliser," so the interesting history belongs to the root. "Sterile" comes from Latin "sterilis," meaning barren or unable to bear offspring, and the word traveled into English through French. "Steriliser" was formed in English by adding the agent suffix "-er" to the verb "sterilise," which itself comes from the same Latin root extended through Late Latin "-izāre" and French "-iser." The verb's suffix has a longer ancestry than the stem. The "-ize" ending descends from a Greek verb-forming pattern that passed into Late Latin and then Old French, arriving in Middle English as "-isen." Speakers in English later attached it to many borrowed stems, and "sterilise" is one of those combinations. The meaning of the root has stayed remarkably close to its origin. A "sterile" field was once one that yielded no crop, and a "steriliser" is now a machine that makes things free of living microbes. The tools took on a modern, medical sense while the core idea of rendering something unable to produce life remained intact.
