hygienic

Sense: adjective/1
All four words describe the absence of dirt or germs, but they sit at different points on a scale. 'Clean' is the everyday word and only promises that something looks or feels free of dirt — a clean shirt may still carry bacteria. 'Hygienic' goes one step further: it specifically means clean enough to stop germs from growing or spreading, which is why you hear it about kitchens, bathrooms, and food handling. 'Sanitary' overlaps closely with 'hygienic' but is more common in formal or public-health language (sanitary inspection, sanitary conditions in a refugee camp). 'Sterile' is the strongest term: completely free of all microorganisms, the standard for surgical tools and operating rooms — far beyond what daily cleaning achieves. Use 'hygienic' for everyday safe-from-germs contexts; reserve 'sterile' for medical settings.

Etymology
Borrowed in the mid-1800s from French 'hygiénique', which in turn comes from Greek 'hygieinos' meaning 'healthful'. The Greek root is tied to Hygieia, the goddess of health in Greek mythology — the same root gives English the noun 'hygiene'. Originally the word was used in medical writing about preserving health; the modern everyday sense of 'free of germs' developed in the late 19th century alongside germ theory and modern sanitation.
