# Kink vs fetish, the difference and where the words come from

> A kink is any sexual interest, practice or fantasy outside the conventional, and the word has no clinical definition. A fetish is narrower, arousal tied to a nonliving object, a material, or a non-genital body part, and it has one, in the DSM-5-TR. Every fetish is a kink; most kinks, spanking or roleplay for instance, are not fetishes.

The two words get used as if they were interchangeable, and in a survey they nearly are: a person who says they have a foot fetish and a person who says feet are their kink are reporting the same thing. In a diagnostic manual they are not close. One word has a page and a set of criteria; the other does not appear at all. That gap is the reason the question keeps getting asked, and it is the reason a straight answer has two halves.

The short version is scope. **Kink covers the whole territory of sexual interest outside the conventional; fetish covers one province of it, arousal tied to a thing.** Kink runs from a preference for a scenario to a preference for a material. Fetish is arousal that is tied to a thing rather than a person or an act. The distinction only becomes useful once it is specific, so the surveys, the manuals and the catalog's own numbers follow.

## What kink means

**Kink is an everyday word for any sexual interest, practice or fantasy that sits outside what a given culture treats as conventional.** It has no clinical definition, no diagnostic criteria and no fixed boundary, so it can cover [roleplay](https://www.kinkspec.com/entry/roleplay), [spanking](https://www.kinkspec.com/entry/spanking), [bondage](https://www.kinkspec.com/entry/bondage), a preference for being watched, and a preference for [leather](https://www.kinkspec.com/entry/leather-fetish), without anyone objecting that these are different kinds of thing. They are, and the word makes no distinction.

The word is younger than it sounds. The [Oxford English Dictionary](https://www.oed.com/dictionary/kinky_adj) and [Etymonline](https://www.etymonline.com/word/kink) trace *kink* to the Dutch word for a twist in a rope, recorded in English as a sailor's term in the 1670s. Thomas Jefferson used it in 1803 for a mental twist or whim. The sexual sense arrives with *kinky* in 1959, and *kink* as a noun for a particular sexual interest follows in the 1970s. Its parent is a metaphor, a bend in something expected to run straight, and it has kept that shape: a kink is defined by the norm it departs from, and norms move.

Because the word is defined against a background, the same interest is a kink in one decade and ordinary in the next. Lehmiller's 2018 survey of 4,175 American adults, summarised in [*Tell Me What You Want*](https://www.sexandpsychology.com/tell-me-what-you-want/), found that only 4 to 7 percent of respondents had never had a fantasy involving BDSM. An interest that most people share is a kink in name only, and the catalog treats it as one because the vocabulary does, and because a reader who types the word wants the page.

## What fetish means

**A fetish is a sexual interest in which the arousal attaches to a nonliving object, a material, or a body part other than the genitals.** The clinical term is [fetishism](https://www.kinkspec.com/entry/fetishism), and in the [DSM-5-TR](https://www.psychiatry.org/psychiatrists/practice/dsm) it appears as Fetishistic Disorder, defined by recurrent, intense arousal from nonliving objects or a highly specific focus on non-genital body parts, persisting for at least six months. The body-part form has its own name, [partialism](https://www.kinkspec.com/entry/partialism). Two exclusions are written into the criteria: garments used in cross-dressing, which belong to [transvestic disorder](https://www.kinkspec.com/entry/transvestic-disorder), and devices designed for genital stimulation.

The word's history is older and stranger than kink's. It comes from the Portuguese *feitiço*, a charm or piece of sorcery, which Portuguese traders applied to West African ritual objects they believed held power. The French philosopher Charles de Brosses coined *fétichisme* in 1760 for the worship of material objects in religion. The erotic sense is a nineteenth-century invention: the neurologists Charcot and Magnan described patients attached to shoe nails, nightcaps and white aprons in 1882, and Alfred Binet, drawing on their cases, coined the sexual meaning in his 1887 essay [*Le fétichisme dans l'amour*](https://en.wikipedia.org/wiki/Sexual_fetishism). So the word has meant, in order, a charm, a god made of wood, and a shoe.

The word *fetish* points at a thing. A person with a [latex](https://www.kinkspec.com/entry/latex-fetish) fetish is aroused by latex, a person with a foot fetish by feet, and in each case the object can be named.

## Where the two overlap

**Every fetish is a kink, because a fetish is a sexual interest outside the conventional, and that is the whole of what kink means. The reverse does not hold.** Most of the interests people call kinks have no object at their centre.

The clearest way to see it is to take the top of the KINKSpec index and ask, of each entry, whether there is a thing. [Dominance and submission](https://www.kinkspec.com/entry/dominance-submission), ranked first of 474 entries, is a dynamic between two people; there is no object. [Bondage](https://www.kinkspec.com/entry/bondage), ranked third, is a practice; rope is its instrument, and for most people who enjoy bondage the rope is a means. [Foot fetish](https://www.kinkspec.com/entry/foot-fetish), ranked fifth, is a fetish in the strict sense, arousal attached to a body part. [Roleplay](https://www.kinkspec.com/entry/roleplay), sixth, is a scenario. [Voyeurism](https://www.kinkspec.com/entry/voyeurism), seventh, is an act of watching. [Spanking](https://www.kinkspec.com/entry/spanking), ninth, is a sensation. Of the ten most documented interests in the catalog, one is a fetish.

The overlap is the gear. The instruments of a practice can become objects of arousal in their own right, and when they do the vocabulary shifts. Someone who likes bondage and someone who has a rope fetish are describing different things, and each would know which they meant. Leather is the classic case: a material worn inside BDSM, and also, for a large organised subculture, a fetish object with bars, codes and titles of its own. The [leather fetish](https://www.kinkspec.com/entry/leather-fetish) entry sits at rank 39, higher than most of the practices leather is worn for.

## How common each one is

**Both words describe interests that are ordinary by the numbers**, which is the finding the surveys keep repeating and the popular picture keeps missing.

[Joyal and Carpentier's 2017 survey](https://www.tandfonline.com/doi/abs/10.1080/00224499.2016.1139034) of 1,040 Quebec adults, weighted to match the province on age, sex, education, ethnicity, religion and residence, found that nearly half of respondents expressed interest in at least one of the eight paraphilic categories the DSM lists, and about a third had acted on one at least once. Voyeurism, fetishism, frotteurism and masochism each drew interest from more than 15.9 percent of respondents, the threshold the authors used for a fantasy to count as statistically unusual, which by the survey's own logic means none of the four is unusual. Interest in fetishism and masochism showed no statistically significant difference between men and women.

Inside fetishism, the distribution is steep. [Scorolli and colleagues' 2007 study](https://www.ebi.ac.uk/europepmc/abstract/MED/17304204) of 381 online fetish discussion groups, covering at least 5,000 participants, found preferences for body parts or features to be the largest category, at about 33 percent, and preferences for objects associated with the body next, at about 30 percent. Feet, and objects associated with feet, were the single most common target of all. Objects unrelated to the body, the kind of thing the word fetish tends to evoke, made up 5 percent.

The catalog's own index reads the same way. Of its 486 entries, 149 carry "fetish" in the name, and they cluster in the middle and lower bands: the ultra-common tier, entries with an estimated prevalence of 20 percent or more, holds 26 entries, and none of them is an object fetish. Foot fetish, at an estimated 14 percent, is the highest-placed fetish in the strict sense, at rank five. The interests above it are all dynamics and acts.

## When a fetish becomes a diagnosis

**The clinical line is distress, and the manuals have moved it twice in a decade.**

The DSM-5, in 2013, made the distinction that the DSM-5-TR of 2022 keeps: a paraphilia is an atypical erotic interest, and a paraphilic disorder is a paraphilia that causes clinically significant distress or impairment, or that involves a non-consenting person. Fetishistic Disorder requires the interest, a six-month duration, and the distress. A person aroused by [feet](https://www.kinkspec.com/entry/foot-fetish) who is untroubled by it has a fetish and no disorder, and the manual says so in its own text. The [ICD-11](https://icd.who.int/browse11), adopted in 2019 and in force since 2022, went further and removed fetishism and fetishistic transvestism as diagnoses altogether, keeping only the paraphilic disorders that involve non-consenting people or that a person finds distressing.

Kink has no clinical line. There is no Kink Disorder because there is no kink criterion, and the interests the word covers reach the manuals only when they coincide with a named paraphilia. [Masochism](https://www.kinkspec.com/entry/masochism), with an estimated prevalence of 23 percent, is in the DSM-5-TR as Sexual Masochism Disorder under the same distress rule; spanking, at 22 percent, is in no manual at all. The difference between them is a clinical history, and the history is the reason one has a Greek name.

## The words in use

In ordinary speech, *fetish* is losing its edges. People say they have a fetish for a body type, an accent, a decade of music, none of which is a fetish in Binet's sense or the manual's. The usage is loose and approving, and it is drifting toward the ground kink already holds. *Kink*, meanwhile, is acquiring a community sense: "the kink community", "kink-aware", *kinky* as an identity rather than a description of an act.

The clinical usage has moved the other way, narrowing. Fetishistic Disorder is a smaller category than the DSM-III's fetishism was, and the ICD-11 has no fetish category at all. **In everyday use *fetish* is widening and in the clinic it is narrowing; *kink* has only ever had the everyday use.**

The catalog keeps both, for the same reason a dictionary does. [Object sexuality](https://www.kinkspec.com/entry/object-sexuality), in which an object is experienced as a partner, gets its own entry because it is neither a kink in the practice sense nor a fetish in the manual's: the object is a partner, which is a different relation from a charged thing. The eleven category families sort every entry by what the interest is about, which is the question the two words were trying to answer.

## Common questions

### Is a fetish the same as a kink?

No. Kink is the broad word for any sexual interest outside the conventional, and it has no clinical definition. A fetish is one kind of kink, arousal tied to an object, a material or a non-genital body part, and it is the only one of the two words that appears in a diagnostic manual.

### Is having a fetish a disorder?

No, on its own. The DSM-5-TR names Fetishistic Disorder, but the diagnosis requires the arousal pattern to last six months and cause clinically significant distress or impairment. A preference for [leather](https://www.kinkspec.com/entry/leather-fetish) or [feet](https://www.kinkspec.com/entry/foot-fetish) without distress is a fetish and not a disorder, and the ICD-11 dropped fetishism as a diagnosis.

### What is the most common fetish?

Feet. Scorolli and colleagues' 2007 study of 381 online fetish groups found body parts the largest category, at about 33 percent, with feet and objects associated with feet the single most common target. On the KINKSpec index [foot fetish](https://www.kinkspec.com/entry/foot-fetish) ranks fifth of 474 entries, with an estimated 14 percent of adults reporting at least mild interest.

### Is BDSM a fetish?

No, not in the clinical sense. [Bondage](https://www.kinkspec.com/entry/bondage), [dominance and submission](https://www.kinkspec.com/entry/dominance-submission) and [spanking](https://www.kinkspec.com/entry/spanking) are practices and dynamics, so they are kinks. The gear used in them, leather, latex, rope, can be a fetish object for some people, which is where the two words meet.

### Where does the word fetish come from?

From the Portuguese *feitiço*, a charm, which traders applied to West African ritual objects. Charles de Brosses coined *fétichisme* for object-worship in religion in 1760, and the psychologist Alfred Binet gave the word its erotic sense in his 1887 essay *Le fétichisme dans l'amour*.

### Where does the word kink come from?

From the Dutch *kink*, a twist in a rope, recorded in English in the 1670s as a sailor's word. The figurative sense of a mental twist or whim dates from 1803, and *kinky* in the sexual sense from 1959, with *kink* as a noun for a sexual interest following in the 1970s.
