The word "PRAC" is commonly spelled with a "C" rather than a "K" in English. This is because the phonetic transcription of the word indicates that the "C" sound is more pronounced than the "K" sound in this case. In IPA phonetic transcription, PRAC is written as /præk/, with the "C" representing the voiceless palatal stop sound. This sound is similar to the "K" sound, but is produced further back in the mouth and with a more abrupt stop.
