Word of the Day: HAPAX LEGOMENON
Pronunciation: UK /ˌhæpæks lɪˈɡɒmənɒn/ |
US /ˌhæpæks lɪˈɡɑːmənɑːn/
Meaning
A hapax legomenon is a word or phrase that appears only once in a particular text or collection of writing. The term is used in linguistics and literary studies, especially when researchers examine old manuscripts, poems and religious texts.
Examples for daily usage
- The researcher identified a hapax legomenon in the ancient manuscript.
- Linguists studied the unusual word as a possible hapax legomenon in the poet's work.
- The rare expression appears only once in the novel, making it a hapax legomenon within that text.
Origin and history
The term hapax legomenon comes from Ancient Greek hapax legomenon, meaning “something said once”. It combines hapax, meaning “once” or “one time”, with legomenon, meaning “something said”.
The expression entered English in the late 17th century. Its use grew in fields such as classical scholarship, biblical studies and historical linguistics, where researchers often encounter words that appear only once in surviving texts.

Cultural significance and modern usage
Hapax legomena are particularly important when studying ancient writing. If a word appears only once in a text, researchers may have little information to help establish its meaning. They must examine the surrounding passage, grammar, related languages and historical context.
Biblical scholars, for example, study words that occur only once in particular versions of the Bible. The same approach is used with ancient Greek poetry, where an unusual word might have been chosen for its sound, rhythm or effect on an audience.
A word does not have to be unique to an entire language to qualify. It might appear just once in a single book, an author's collected works or a particular body of historical writing.
The term is also used in modern corpus linguistics, which studies large collections of written or spoken language to understand how words are used.
Interesting facts
Hapax legomena is the plural form of hapax legomenon. One occurrence is a hapax legomenon; several are hapax legomena.
The shorter form hapax is also used. Its plural can be hapaxes.
The related term dis legomenon refers to a word or form recorded twice in a particular text or corpus.
Tris legomenon refers to something recorded three times, while tetrakis legomenon refers to four occurrences.
