smelling
The act of inhaling air with the nose to determine what a particular scent is. Smells can be perceived when odor molecules bind to hair-like neurons in the nose called cilia. Pleasant smells can invoke happiness and nostalgia, while bad odors can cause revulsion and force the person to cover their nose. It is of the five senses, also called olfaction.
