The spelling of the surname "Sandidge" can be a bit confusing for non-native English speakers. The first syllable is pronounced like "sand" (/sænd/, with the 'a' pronounced like the word "man") and the second syllable is pronounced like "idge" (/ɪdʒ/). The 'e' at the end of the name is silent. This surname is often spelled with two 'd's, but it can also be spelled "Sandige" or "Sandage".
