Something that's antibacterial works by killing bacteria or keeping it from growing. You might put antibacterial ointment on a cut to help keep it clean and free from infection.
Officially, an antibiotic like penicillin is an antibacterial agent — it kills bacteria, microorganisms that cause disease. You're more likely to find the word antibacterial describing special soaps and lotions that don't just wash bacteria off your hands, but actually kill them. The word combines anti-, “against,” and bacterial, from the Greek root bakterion, “small staff,” which describes the shape of the first bacteria seen through microscopes.
