cleaner
UK: ˈkliːnə | US: ˈkliːnər
n. a person or thing that cleans
n. a substance or device used for cleaning
adj. comparative form of "clean" (more clean)
The word "cleaner" combines the root "clean," derived from Old English clǣne (pure, free from dirt), with the agentive suffix "-er," which originates from Old English -ere (indicating a person or tool performing an action). The suffix "-er" is productive in forming nouns for professions or tools (e.g., "teacher," "blender"). The word's evolution reflects a straightforward compounding logic: "one who or that which cleans."
