Etymology
Origin of fungicide
Explanation
Any substance that's used to kill spores is a fungicide. If your beautiful roses are dying because mildew is attacking their leaves, you might need to spray them with a fungicide. The word fungicide is formed by taking fungus, "a mushroom" in Latin, and adding the suffix -cide, or "killer." So just like matricide means killing one's mother and pesticide means something that kills bugs, fungicide means something that kills fungi. Whether you have a fungus growing on your bathroom ceiling or your tomato plants, you probably need a fungicide to get rid of it.
