The spelling of the word "Donaline" can be explained using IPA phonetic transcription. The word begins with the voiced dental fricative /ð/ followed by the monophthong vowel /əʊ/. The third syllable consists of the voiced alveolar nasal /n/ followed by the unstressed syllable schwa /ə/. The final syllable is made up of the voiceless alveolar plosive /t/ followed by the unstressed syllable schwa /ə/. Thus, the correct spelling of the word is "Donaline" with the stress on the second syllable.
