Sexagesimal

Part of speech: adjective

Pronunciation: /ˌsɛk.səˈdʒɛ.sɪ.məl/

Definitions

  1. Relating to a numeral system based on sixty, this term describes both the system itself and the angles measured in degrees or divisions of time like minutes and seconds
  2. This term is associated with a numerical base of sixty, referring to both the system's structure and its application in measuring angles and time
  3. Connected to a counting system using sixty as its base, it encompasses the method of measurement for angles as well as subdivisions of time into minutes and seconds

Etymology: The adjective in question traces its origins to a Latin numerical system based on the number sixty. The root "sexagesimus" in Latin means "sixtieth," derived from "sexaginta," meaning "sixty." This numerical foundation connects directly to the ancient practice of counting or measuring in units of sixty, an approach that dates back to the Babylonians, who used a base-60 system for mathematics and astronomy. This base-60, or sexagesimal, system profoundly influenced the way we measure time and angles even today. For example, there are 60 seconds in a minute and 60 minutes in an hour, as well as 360 degrees (which is 6 times 60) in a circle. The term emerged in English during the 17th or 18th century as scholars and mathematicians sought to describe this numerical base distinctly, especially in the context of trigonometry, astronomy, and early computational methods. The suffix "-al" transforms the Latin root into an adjective, signaling something pertaining to or based on sixty. This morphological process is common in English for creating adjectives from Latin or Greek roots, allowing the term to be used in technical descriptions. Thus, it came to describe mathematical or measurement systems that rely on the number sixty rather than the more familiar decimal system based on ten. Overall, the story of this word is intertwined with human efforts to understand and quantify the world using the sexagesimal system, a legacy of ancient civilizations whose influence persists in modern science and everyday timekeeping.
