What does osmatic mean?
Osmatic is a rare adjective relating to smell or the sense of smell. It is used chiefly in scientific, technical, and specialized writing, especially when discussing the detection of odors, olfactory responses, or the chemical signals through which organisms perceive their surroundings. The word can also describe something that produces a noticeable smell, although this sense is less common in modern English. In ordinary speech, “olfactory” is often the clearer and more familiar alternative, while “odoriferous” is useful for something that emits a strong smell. Osmatic comes from the same ancient Greek root associated with smell and the process perceived as odor. Although it may occasionally be confused with “osmotic,” the two words belong to different technical concepts: one concerns the sense of smell, and the other concerns osmosis.
Relating to the sense of smell or to olfaction.
"The compound attracts pollinators through an osmatic signal."
Chiefly used in technical and scientific contexts.
Having or producing a strong or noticeable smell.
"The plant releases an osmatic substance that deters herbivores."
This sense is uncommon and is more characteristic of specialized or historical usage.
Osmatic preserves the Greek idea of smell in modern science: it belongs to the family of words that made the invisible world of odors measurable.

Etymology of osmatic
Osmatic derives from Ancient Greek osmē, meaning “smell” or “odor,” through the combining form osmat-. The same root also underlies English words such as osmosis and osmometer, although those words refer specifically to the movement of a solvent through a membrane or to the measurement of osmotic pressure. The adjective entered English through scientific and medical vocabulary.
How osmatic is actually used
This is a rare, formal or technical adjective. It is more common in specialized scientific writing than in everyday English; when describing something simply as having a strong smell, “odoriferous” is usually more natural.
