How this list was compiled: We chose and wrote this list of 150 fears ourselves: 126 named fears and 24 plain everyday fears for story characters. The named fears and the things feared were checked on 2026-09-18 against https://en.wikipedia.org/wiki/List_of_phobias. Every word root, and each name that is missing from that list, was checked the same day against the word's own entry or its combining form on https://en.wiktionary.org/ (for example https://en.wiktionary.org/wiki/arachnophobia and https://en.wiktionary.org/wiki/cyno-). Coining facts come from the same pages and from the English Wikipedia articles Nomophobia, Trypophobia (https://en.wikipedia.org/wiki/Trypophobia), Triskaidekaphobia, Tetraphobia and Heptadecaphobia, checked 2026-09-18. Decidophobia was checked again on 2026-09-19: https://en.wiktionary.org/wiki/decidophobia gives decide plus -phobia, and https://en.wikipedia.org/wiki/Walter_Kaufmann_(philosopher) lists his 1973 book Without Guilt and Justice: From Decidophobia to Autonomy, so the card is tagged as a modern coinage and not as a joke. The four names tagged as jokes (Aibohphobia, Anatidaephobia, Arachibutyrophobia and Hippopotomonstrosesquipedaliophobia) all sit in the jocular and fictional section of the Wikipedia list, checked 2026-09-19. How psychiatry sorts phobias follows https://en.wikipedia.org/wiki/Specific_phobia, checked the same day. A name went on the list only when a root could be confirmed, or when the dictionary itself says the root is unknown. Terms for prejudice against groups of people, sexual terms and medical conditions were left out on purpose. Greek words are written in plain Latin letters without accents. The everyday fears and their story notes are our own writing and are not drawn from any source. These are names for fears, not diagnoses, and nothing here describes symptoms or treatment. The root-language chips follow our own sorting of each root: Modern Greek counts as Greek, Scientific Latin as Latin, a name with a root from each sits under both, and English, Irish and unknown roots are Other.

How it works

Five fears come up from the 150 in this random phobia generator: 126 named fears, from arachnophobia to the fear of the number 17, plus 24 everyday fears for characters. Each named card says what is feared and which Greek or Latin word built the name. Root languages are under More filters.

Most phobia names are coinages, not diagnoses

Almost any Greek word can take -phobia on the end, so new names keep arriving. In 1897 the American Journal of Psychology was already mocking the habit of giving every feared object a Greek name. Trypophobia was coined on a forum in 2005. The DSM-5, psychiatry's standard manual, keeps no such list. It sorts specific phobias into five types: animal, natural environment, blood and injection, situational and other.

Everyday fears for story characters

As a random fear generator for fiction, choose Everyday fears in the list for 24 plain ones, such as being late or opening the mail. Each card carries a story note instead of a root. A fear earns its place when the plot forces the character to face it, so draw a random scenario next.

For a quiz round, press Hide all meanings and let teams guess it from the name. Hexakosioihexekontahexaphobia is fair once they hear it spells a number.
Writing a character? Draw one named fear and one everyday fear. The first hands you a scene, the second a habit that shows on every page.

Questions and answers

Are these real phobias?

They are real words, and most are not medical terms, which is why the page says named fears. A few, such as agoraphobia, are used in medicine. Four are outright jokes and carry a Joke name badge, such as aibohphobia, a fear of palindromes that is itself a palindrome. Nothing here describes symptoms or treatment, and a draw says nothing about you.

Why do some fears have two names?

Usually because one name was built from Greek and the other from Latin. Bees get melissophobia from Greek melissa and apiphobia from Latin apis, and sleep gets hypnophobia and somniphobia. The ending -phobia is Greek, so a Latin front half makes a mixed word, and claustrophobia is one of those.

What is the longest name on the list?

Hippopotomonstrosesquipedaliophobia, a joke name for the fear of long words, at 35 letters. It stretches sesquipedalian, from Latin for a foot and a half long, by adding a hippopotamus and a monster. The longest name that is not a joke is hexakosioihexekontahexaphobia, the fear of 666, at 29 letters.
