What is the root word for "sanitizer"?

The root word for "sanitizer" is "sanitize." In this context, "sanitize" refers to the process of making something clean and safe by reducing harmful microorganisms. The term "sanitizer" is derived from "sanitize," indicating a substance or agent that performs this cleaning function.

While "sanitation" is closely related, it specifically refers to the measures taken to ensure cleanliness and hygiene. "Sanctify" pertains to making something holy, which is unrelated to cleaning practices, and "sanctuary" refers to a sacred or safe place, also not connected to the concept of cleaning or disinfecting. Therefore, "sanitize" is the most accurate root word, as it directly relates to the action taken by a sanitizer.
