The spelling of the word "Frandsen" can be confusing for non-native English speakers. The phonetic transcription of this word is /ˈfrændsən/. The first syllable "frand" is pronounced with a short "a" sound, like in "frantic". The second syllable "sen" is pronounced with a soft "s" sound, like in "sense". The "-en" ending is pronounced as a schwa sound /ən/. Therefore, the correct spelling of this word is "Frandsen", with an "a" in the first syllable and "sen" in the second syllable.
