"Hardge" is a surname with a somewhat unusual spelling, but it is pronounced just as it looks. The "h" is silent, so the word begins with the "ar" sound, as in "car". The "d" is pronounced like a "j" sound, as in "judge", and the "g" is pronounced like a "zh" sound, as in "treasure". Therefore, the IPA transcription for "Hardge" would be /'ɑr.dʒə/. While this spelling may seem unfamiliar to some, it is important to respect and correctly pronounce all names.
