The spelling of the word "MEXHP" is a bit unusual, but it can be explained using IPA phonetic transcription. The first two letters, "ME," are pronounced as /mi/ and the following three letters, "XHP," are pronounced as /ksʰp/. The "X" represents a voiceless velar fricative sound, similar to the "ch" in "loch," and the "H" represents a voiceless glottal fricative sound. Altogether, these sounds create the unique spelling of "MEXHP."
