Fragrance Glossary A to Z: Every Term, Plainly Explained

Updated June 2026

A fragrance glossary defines the recurring vocabulary used to describe how a perfume smells and behaves. The core terms split into a few groups: structure (note, accord, top/heart/base notes, fragrance pyramid, dry-down), performance (longevity, projection, sillage), strength (extrait, eau de parfum, eau de toilette, eau de cologne), and scent families (chypre, fougere, gourmand, amber, oud, animalic, aldehydic). Knowing these lets you read any review or note list and predict, roughly, how a scent will wear.

Fragrance writing is full of words that sound technical but mostly describe simple, observable things: how long a scent lasts, how far it travels, what stage of the wear you are smelling, and which broad family it belongs to. Once you know the vocabulary, a note list or a review stops being a wall of jargon and becomes a fairly reliable forecast of how a bottle will behave on your skin. This glossary collects the terms you keep running into — from accord and sillage to chypre, oud, and flanker — and defines each in one or two plain sentences, with no hype and no insider gatekeeping. It is organized in loose groups rather than strict alphabetical order, because the words make more sense when you see them next to their relatives: structure terms together, performance terms together, strength tiers together, and scent families together. Use it as a reference you come back to, and as the hub that the rest of our fragrance section links to whenever a guide uses one of these words.

Structure: note, accord, and the fragrance pyramid

A note is a single recognizable scent element — bergamot, rose, or sandalwood, for example — used as a building block in a fragrance. An accord is a balanced blend of several notes that the nose reads as one unified smell, such as a 'leather' or 'amber' accord; the term is borrowed from the musical idea of a chord, where separate sounds combine into one. Many materials show up as accords rather than single ingredients because they cannot be distilled directly: there is no way to extract a scent from actual leather, so a 'leather' accord is built from other notes that, together, read as leather. A fragrance pyramid (also called a note pyramid) maps a scent into three tiers by how fast each part evaporates: top notes, heart notes, and base notes. Top notes are the first, lightest, and most volatile impression you smell on application, and they fade the fastest — often within minutes. Heart notes, also called middle notes, form the main body or core of the fragrance and emerge as the top notes fade; florals and spices are common heart notes. Base notes are the heaviest, longest-lasting materials that give a scent depth and anchor it to the skin, with woods, musk, vanilla, and resins among the usual examples. Dry-down refers to the final stage of the wear, once the top and heart notes have evaporated and only the base notes remain — it is how a fragrance smells hours after you sprayed it, and often the part that matters most for whether you keep reaching for a bottle.

Performance: longevity, projection, sillage, and throw

These three words describe how a fragrance behaves in time and space, and people mix them up constantly. Longevity is how long a fragrance stays detectable on your skin; it is influenced by the perfume-oil concentration, the quality of the ingredients, and your own skin chemistry, which is why two people can get different mileage from the same bottle. Projection is how far a fragrance radiates outward from your skin in the moment — the size of the scent bubble around you right now. Sillage (French for 'wake' or 'trail,' pronounced roughly 'see-yazh') is the trail of scent a fragrance leaves behind in the air as you move or after you have already passed by; the key difference is timing and place, since projection is what is around you now and sillage is what lingers where you have been. Throw is informal slang for how strongly a fragrance projects into the surrounding air — when someone says a scent has 'great throw,' they mean it carries well. A useful mental model: projection is the room noticing you when you walk in, sillage is the room still noticing after you have left, and longevity is whether you can still smell it on yourself at dinner. None of these is automatically 'better' — a quiet, close-wearing scent and a loud, far-reaching one simply suit different settings.

Strength tiers: extrait, EDP, EDT, EDC, and eau fraiche

Concentration describes how much perfume oil is dissolved in the alcohol base, and the labels on a bottle map to that. From highest oil load to lowest, the conventional tiers are: parfum or extrait de parfum, eau de parfum (EDP), eau de toilette (EDT), eau de cologne (EDC), and eau fraiche. Extrait de parfum — also called 'parfum' or 'pure perfume' — carries the highest oil concentration and is typically the strongest and longest-lasting tier. Eau de parfum (EDP) sits just below extrait and is the most common modern strength for both designer and niche releases. Eau de toilette (EDT) is lighter than EDP, generally projecting and lasting for a shorter time, which makes it a common daytime and warm-weather choice. Eau de cologne (EDC) is a light, low-concentration style, traditionally citrus-forward — and note that 'cologne' is also used loosely in everyday speech to mean 'men's fragrance,' regardless of the actual concentration, so read the label rather than the casual word. The shopping shortcut: read the tiers in the order above, from extrait down to eau fraiche, and remember that a higher tier buys longevity and richness, not necessarily a smell you will like more.

Scent families: chypre, fougere, gourmand, amber, oud, and more

Olfactory refers to the sense of smell, and an 'olfactory family' is a category that groups fragrances by their dominant character — the families below are the ones whose names show up most often. A chypre (pronounced 'sheep-ruh') is a classic family built on the contrast of bright citrus top notes over an oakmoss-and-labdanum base; the name comes from the island of Cyprus. A fougere (pronounced 'foo-zhair,' French for 'fern') is built around lavender, oakmoss, and coumarin — often from tonka bean — and forms the backbone of many 'barbershop' masculine scents. Gourmand describes fragrances featuring edible, dessert-like notes such as vanilla, caramel, chocolate, or sugar. Amber, as a perfumery accord, is a warm, sweet, resinous blend often built from labdanum, vanilla, and benzoin; despite the name, it is not fossilized tree resin in this olfactory sense. Animalic notes are warm, musky, sometimes raw or 'skin-like' facets historically derived from animal sources such as musk, civet, and castoreum, and now usually recreated synthetically. Oud (also spelled oudh, and known as agarwood) is a dark, woody, resinous material that forms when Aquilaria trees become infected with mold; it is prized, expensive, and central to many Middle Eastern fragrances. Aldehydes are synthetic aroma compounds that add a sparkling, soapy, waxy, or champagne-like lift, and they are famously prominent in Chanel No. 5. The table below pairs each family with a widely cited reference scent so the abstract word has something concrete attached to it.

Shopping and hobby slang: niche, designer, flanker, blind buy, and more

These are the words that come up once you start actually buying — and the ones reviewers use without explaining. Niche fragrances are made by smaller, specialized houses that emphasize unusual materials and artistic composition, while designer fragrances are produced under fashion or lifestyle brands for broad, mass-market appeal; the line between them is about scale and intent, not a guarantee of quality either way. A flanker is a new fragrance released as a variation of an existing successful scent, usually sharing the original's name with an added qualifier — an 'Intense' or seasonal edition, for instance — and it can smell quite different from the original it spun off. A nose (French: 'nez') is the common term for a perfumer, the person who actually composes a fragrance. Maceration is the aging of a finished perfume concentrate, and the blending of the oils with alcohol, before bottling; it can deepen and round out the scent, which is why some people 'rest' a new bottle before judging it. A blind buy is purchasing a fragrance without having smelled it first — convenient, but a gamble. A scrubber is slang for a fragrance the wearer dislikes so strongly they want to scrub it off their skin. Finally, two terms about your own nose: anosmia is the inability to smell at all, while 'olfactory fatigue' (also called nose blindness) is the temporary inability to detect a scent after prolonged exposure to it — the reason you stop smelling your own perfume an hour after spraying it, even though others still can.

How to use this glossary with the rest of the section

The point of learning these words is not to sound expert — it is to read a note list or a review and form a realistic expectation before you spend money. A practical reading order: start with the strength tier on the label to gauge roughly how long and how loud a scent will be, scan the note pyramid to see what you will smell at each stage (especially the base notes, since the dry-down is what you live with), and check the family to know the overall mood. If a review praises a scent's sillage but you mostly wear fragrance to a close, shared office, that is a signal to look closer or test first rather than blind buy. When any of our other fragrance guides use one of these terms — in a concentration explainer, a chypre or gourmand roundup, a flanker comparison, or a niche-versus-designer breakdown — they link back to this page, so you can always check a definition without losing your place. Bookmark it, and treat the comparison table below as a quick-reference card pairing each scent family with a widely cited reference scent.

Frequently asked

What is the difference between projection and sillage?

Projection is how far a fragrance radiates outward from your skin in the moment — the size of the scent bubble around you right now. Sillage is the trail of scent it leaves behind in the air as you move or after you have already passed by. In short, projection is the room noticing you when you arrive; sillage is the room still noticing after you leave.

What do top, heart, and base notes mean?

They are the three tiers of a fragrance pyramid, sorted by how fast each part evaporates. Top notes are the first, lightest impression and fade fastest, often within minutes; heart (middle) notes form the main body and emerge as the top fades; base notes are the heaviest, longest-lasting materials — woods, musk, vanilla, resins — that anchor the scent and define the dry-down hours later.

What is an accord in perfume?

An accord is a balanced blend of several notes that the nose reads as a single unified smell, like a 'leather' or 'amber' accord; the term is borrowed from the musical idea of a chord. Many materials exist only as accords because they cannot be distilled directly — a 'leather' accord, for example, is built from other notes rather than extracted from actual leather.

What is the difference between niche and designer fragrances?

Niche fragrances are made by smaller, specialized houses that emphasize unusual materials and artistic composition, while designer fragrances are produced under fashion or lifestyle brands for broad mass-market appeal. The distinction is about scale and intent, not a guarantee of quality — there are excellent and ordinary examples on both sides.

What is a flanker?

A flanker is a new fragrance released as a variation of an existing successful scent, usually sharing the original's name with an added qualifier such as 'Intense' or a seasonal edition. Despite the shared name, a flanker can smell quite different from the original it spun off, so it is worth testing rather than assuming it is just a stronger version.
