The English suffixes -phobia, -phobic, -phobe (of Greek origin: φόβος/φοβία ) occur in technical usage in psychiatry to construct words that describe irrational, disabling fear as a mental disorder (e.g., agoraphobia), in chemistry to describe chemical aversions (e.g., hydrophobic), in biology to describe organisms that dislike certain conditions (e.g., acidophobia), and in medicine to describe hypersensitivity to a stimulus, usually sensory (e.g., photophobia). In common usage they also form words that describe dislike or hatred of a particular thing or subject. The suffix is antonymic to -phil-.

Many people apply the suffix -phobia inappropriately to mild or irrational fears with no serious substance; however, earlier senses relate to psychiatry which studies serious phobias which disable a person's life. For more information on the psychiatric side of this, including how psychiatry groups phobias as agoraphobia, social phobia, or simple phobia, see phobia.

The following lists include words ending in -phobia, and include fears that have acquired names. In many cases people have coined these words as neologisms, and only a few of them occur in the medical literature. In many cases, the naming of phobias has become a word game, of notable example being a 1998 humorous article published by BBC News.

Note too that no things, substances, or even concepts exist which someone, somewhere may not fear, sometimes irrationally so. A list of all possible phobias would run into many thousands.

Most of these terms tack the suffix -phobia onto a Greek word for the object of the fear (some use a combination of a Latin root with the Greek suffix, which many classicists consider linguistically impure).

In some cases (particularly the less medically-oriented usages), a word ending in -phobia may have an antonym with the suffix -phil-, e.g., Germanophobe / Germanophile.

Phobia lists

A large number of-phobia lists circulate on the Internet, with words collected from indiscriminate sources, often copying each other. Also, a number of psychiatric websites exist that at the first glance cover a huge number of phobias, but in fact use a standard text to fit any phobia and reuse it for all unusual phobias by merely changing the name. Such practice is known as content spamming and is used to attract search engines.

Psychological conditions

In many cases specialists prefer to avoid the suffix -phobia and use more descriptive terms, see, e.g., personality disorders, anxiety disorders, avoidant personality disorder, love-shyness.


Non-psychological conditions

The following medical conditions have nothing to do with irrational fears. However, each usually has a psychological disorder of the same name which is an irrational fear. The behavior of an individual with the medical condition can be similar to the behavior of an individual with the psychological disorder of the same name (e.g., for both usages of Photophobia the person avoids light). The difference in usage is that for the medical term there is an underlying physiological condition that results in the behavior. For example, with medical Photophobia the hypersensitivity to light is sufficient such that at some light levels the person experiences pain which they avoid by seeking darkness. Removing the physiological cause of the hypersensitivity to light results in the person no longer avoiding light. With psychological Photophobia the person fears the light even though there is no current physiological pain caused by light.

Biology, chemistry

Biologists use a number of -phobia/-phobic terms to describe predispositions by plants and animals against certain conditions. For antonyms, see here.


One can readily use the suffix -phobia to coin a term that denotes a particular anti-ethnic or anti-demographic sentiment, such as Francophobia. Often a synonym with the prefix "anti-" already exists (e.g., Polonophobia vs. anti-Polonism). See "List of anti-ethnic terms" for more examples. Anti-religious sentiments are expressed in terms such as Christianophobia and Islamophobia.
