The spelling of the word "Matthies" may seem confusing to some, but it is actually quite easy to understand with the help of IPA phonetic transcription. The first sound, "m," is a bilabial nasal consonant made by closing the lips and allowing air to pass through the nose. The next sound, "a," is a short vowel pronounced as a clear "ah" sound. The following two sounds, "th" and "ie," are a bit tricky. "Th" represents the voiceless dental fricative sound and "ie" is pronounced as "ee." Finally, "s" is a voiceless alveolar sibilant. Altogether, "Matthies" is pronounced as "m-ah-th-ee-s."
