Lacking smell or having no odor; not producing or having any scent.
From Greek 'a-' (without) plus 'osme' (smell or odor). This adjective is relatively rare in modern English but was used in scientific and philosophical contexts to describe things without olfactory properties.
While many gases and substances are colorless and invisible, calling something 'aosmic' specifically highlights the absence of smell—a property that can be surprisingly important in identifying pure chemicals or detecting contamination.
