The spelling of the word "frauder" can be explained using the International Phonetic Alphabet (IPA). The word is pronounced as /ˈfrɔːdə(r)/ where the first syllable is stressed. The sound /frau/ is commonly spelled as "fraud" and is used to describe deceit or dishonesty. However, the addition of the suffix "-er" changes the meaning of the word to someone who commits fraud, making "frauder" an uncommon but valid spelling of the word.
