What is aromas?

An aroma is an odor arising from spices, plants, food and so on. Like the smell of perfume, the smell of that morning brew of coffee, the Mexican food you smell your neighbors cooking or even a fart. Yes.. A fart.

An aroma is typically a good smell, but not always.

Aromas are basically multiple odors. For example: The aromas found in a men's public bathroom can smell quite awful. (I don't want to go into further detail on that one! But your mind can wonder what multiple smells are in there.)
