The word "pill cocciae" may seem complex, but its spelling can be explained through IPA phonetic transcription. /pɪl/ represents the initial sound of the word, "pill." /kɒkˈsaɪi/ represents "cocciae," which is the plural form of cocci, a type of bacteria. The "c" sound in "cocciae" is pronounced as /k/, and the "cc" produces a doubled "k" sound. The "o" in "cocciae" is pronounced as /ɒ/ and followed by the "cc" sound, producing a slightly elongated pronunciation. Lastly, "ae" is pronounced as /aɪ/.
