Usage

What does hendeca- mean? Hendeca- is a combining form used like a prefix meaning “eleven.” It is occasionally used in technical terms, especially in mathematics. Hendeca- comes from the Greek héndeka, meaning “eleven.” The Greek héndeka, in turn, is ultimately a combination of the Greek hén, meaning “one,” and  déka, meaning “ten.”Although hén is the Ancient Greek word for “one,” the combining form mono-, from Greek mónos, “alone” or “only,” is typically used to signify “one” in English. Déka similarly gives us the combining form deca-. Find out more about mono- and deca- at our Words That Use articles for each. What are variants of hendeca-?When combined with words or word elements that begin with a vowel, hendeca- becomes hendec-, as in hendecarchy.
