The spelling of the word "PFADD" can be confusing, as it includes two consonants that are rarely seen together in English. In phonetic transcription, "PFADD" is spelled /pfæd/. The "P" and "F" together create a sound similar to the "P" sound in "pat," but with a bit of extra air expelled. The "DD" at the end is pronounced like a hard "T" sound in English, though in German (where the word comes from) it's pronounced more like a "D."
