Cynobex (IPA: /ˈsaɪnoʊbɛkʃ/) is a theoretical compound word that combines the Greek word "kyon" (meaning "dog") and the Latin word "obex" (meaning "obstacle"). The spelling of cynobex includes a "y" instead of an "i," which is a common way to represent the /aɪ/ sound in English. The "obex" portion of the word is spelled with an "o" instead of a "u," which is also common in English when Latin roots are used. The final "s" sound is represented with an "x," which can indicate a plural form or a different grammatical function.
