The spelling of the word "ADDOCI" may seem peculiar at first, but it can be explained through the use of IPA phonetic transcription. The word is pronounced as /ˈæd.ə.sɪ/, with the stress on the second syllable. The spelling follows the phonetic rules of English language, with the double "d" representing a voiced dental stop and the "ci" representing a soft "s" sound. This unique spelling is likely a product of etymology and the evolution of language over time.
