The word "koppes" is spelled with a double "p" to indicate the pronunciation of the "o" as a short vowel. In phonetic transcription, it is represented as /ˈkɑpəs/. The first syllable is stressed, and the second syllable ends with an "s" sound. The word is sometimes spelled with a single "p," but this can lead to confusion with other words. "Koppes" is a lesser-known word that means "heads" in Dutch, and is occasionally used in English in reference to the head of a barrel or cask.
