The spelling of the word "Regner" follows the International Phonetic Alphabet (IPA) phonetic transcription. In IPA, "R" represents the voiced alveolar trill /r/, "e" represents the close-mid front unrounded vowel /e/, "g" represents the voiced velar stop /ɡ/, "n" represents the voiced alveolar nasal /n/, and "er" represents the reduced vowel schwa /ər/. Therefore, the spelling of "Regner" accurately reflects the pronunciation of /ˈrɛɡnər/, which is commonly used as a given name in Scandinavian countries.
