The word "Dirksen" is spelled with the IPA phonetic transcription of /dɜrksən/. It starts with a voiced dental fricative "d" sound, followed by an unstressed "ɜr" vowel sound, then a voiceless velar fricative "k" sound, and an unstressed "sən" ending with a schwa vowel sound. The spelling of "Dirksen" is not related to the pronunciation but rather the origin of the surname. Its German roots suggest it was originally spelled as "Dirksen" or "Dierksen," with the "-en" suffix signifying the patronymic surname.
