sesquipedale

Sesquipedale is a Latin adjective form meaning “one and a half feet long.” It is the neuter singular form of sesquipedalis, and it would modify neuter nouns in Latin. The term derives from sesqui- (“one and a half”) combined with pes/pedis (“foot”).

In linguistic and taxonomic contexts, sesquipedale has historically appeared as a descriptor in Latin descriptions, particularly in botany and zoology. It would be used to indicate that a particular feature, such as a stem, stalk, or leg, is notably long. Today, the use of sesquipedale in new scientific names is rare, with more precise measurements or modern terminology preferred in contemporary descriptions. When encountered in older or translated texts, sesquipedale generally conveys the literal sense of “one and a half feet long.”

In English, the related word sesquipedalian—meaning given to long words or to long-winded style—is far more common. Sesquipedale is thus primarily of interest to readers studying Latin descriptors, historical taxonomy, or the linguistic origins of related terms. It is not a commonly used term in everyday language, but it helps illustrate how Latin epithets can convey explicit measurements within scientific naming or descriptive passages.
