Why Smells Seem So Hard to Describe
Some languages are better at naming smells because they contain dedicated words for odor qualities, much as English has basic terms such as red, green, and blue. English speakers, by contrast, usually identify a smell by naming its likely source: coffee, smoke, roses, wet earth, or something less pleasant.
This difference does not mean English speakers have weaker noses. It means English gives them fewer convenient labels for organizing and communicating what their noses detect. The difficulty is primarily linguistic and cultural rather than a universal limitation of human perception.
English Usually Names the Source
Imagine opening an unmarked bottle and smelling cinnamon. An English speaker will probably say, “It smells like cinnamon.” That answer identifies the substance believed to be producing the odor, but it does not name the smell as an independent quality.
We use the same strategy constantly:
- It smells like freshly cut grass.
- It has a coffee-like aroma.
- There is a hint of smoke.
- The room smells like old books.
- The air has a lemony scent.
English has general odor words, including aroma, fragrance, stench, scent, and odor. Yet these usually tell us whether a smell is present or whether it is pleasant. Even more descriptive terms—such as floral, fruity, woody, and citrusy—are connected to familiar sources.
Other common descriptors are borrowed from different senses. A smell may be sweet, sharp, warm, heavy, or bright. These words are useful, but they do not form a precise, widely shared system of basic smell categories.
Jahai Treats Odors More Like Colors
Jahai, a language spoken on the Malay Peninsula, has become a particularly important example in the study of smell vocabulary. Its speakers use abstract terms that apply to odor qualities found across several unrelated sources.
In a well-known experiment, researchers asked Jahai and English speakers to name colors and odors. The Jahai speakers named smells with roughly the same consistency that they named colors. English speakers were considerably less consistent when discussing odors, often producing uncertain or source-based answers.
The Max Planck Institute’s summary of the Jahai research explains why the familiar claim that smells are impossible to describe does not apply equally across cultures. People can name odors efficiently when their language supplies conventional categories for doing so.
For Jahai speakers, a basic smell term can group together several things that share an olfactory quality, even when those things look different and serve different purposes. This resembles the way English speakers call leaves, traffic lights, gemstones, and paint green without needing to identify one green object as the standard.
Maniq Has a Structured Smell Vocabulary
Maniq, spoken by a hunter-gatherer community in southern Thailand, also possesses a specialized odor vocabulary. Researchers have documented at least 15 abstract expressions used to classify smells.
A Maniq odor term may apply to mushrooms, rotten wood, an old shelter, animal skin, or a bamboo container. The shared quality is not the objects themselves but the kind of smell they produce. Other terms connect odors associated with food, vegetation, raw meat, blood, or smoke.
According to an overview of the Maniq odor lexicon, this vocabulary is organized partly around pleasantness and danger. That structure makes practical sense in an environment where odors can reveal spoiled food, medicinal plants, nearby animals, or other important conditions.
These categories may appear “untranslatable” because English needs a list of examples to explain what one Maniq word communicates. Similar mismatches can be found among words with no simple English equivalent. Translation becomes difficult when two languages divide experience in different ways.
Culture Determines Which Distinctions Matter
Languages develop vocabulary for subjects that their communities discuss regularly. English has detailed terminology for law, technology, finance, organized sports, and countless specialist fields. Smell, however, often occupies a less prominent place in everyday English conversation.
For communities living close to forests, plants, wildlife, and changing environmental conditions, odor may carry immediate practical information. People who repeatedly discuss that information need stable, shared categories. Children hear the terms, learn which smells belong together, and pass the system to the next generation.
This does not mean every community living in a forest must develop abstract smell words. Environment alone cannot explain vocabulary. Social customs, history, subsistence practices, and inherited linguistic patterns all contribute to the distinctions a language preserves.
Food offers a familiar English-language comparison. Cooks, coffee professionals, perfumers, and wine experts build specialized vocabularies because their work requires careful sensory distinctions. The connection between sensory experience and terminology is also visible in the descriptive language surrounding food.
Words Make Smells Easier to Retrieve
Naming an odor involves more than detecting it. A person must recognize a sensory pattern, connect it to a concept, and retrieve an appropriate word. English speakers often recognize a smell as familiar while being unable to say what it is. The name may suddenly become obvious once someone provides a clue.
Dedicated vocabulary makes this retrieval process more efficient. If a community has a familiar label for a recurring odor category, speakers do not have to search mentally through possible objects. They can access the category directly.
Language may therefore guide attention and memory without completely controlling perception. Having a word does not give someone a new nose, while lacking one does not make an odor undetectable. Instead, vocabulary makes particular distinctions easier to notice, remember, compare, and communicate. This nuanced relationship is central to discussions of how language can influence thought.
English Can Become More Smell-Conscious
English may lack a compact everyday odor system, but its speakers are not condemned to vague descriptions. Anyone can develop a richer personal vocabulary through deliberate practice.
Start by smelling everyday materials without looking at them. Rather than immediately guessing the source, describe the odor’s qualities. Consider its intensity, pleasantness, freshness, familiarity, and emotional effect. Ask whether it seems dry, damp, clean, fermented, resinous, mineral, green, animal-like, or smoky.
Then compare several odors and identify shared characteristics. This moves the task from naming objects to forming categories. Perfumers, chefs, and other sensory specialists learn partly through repeated comparison and discussion.
The larger lesson is that languages do not merely attach labels to a world already divided into obvious parts. They help communities decide which similarities deserve names. English notices some distinctions with remarkable precision and leaves others loosely defined. Languages such as Jahai and Maniq show that the apparently indescribable world of smell becomes far easier to discuss when speakers possess the words—and the cultural reason—to describe it.
