The spelling of the word "nose dove" may appear confusing at first. However, by looking at its phonetic transcription in IPA (nəʊz dʌv), the spelling becomes clearer. The first syllable "nose" is pronounced with a diphthong (əʊ) and the second syllable "dove" is pronounced with a reduced vowel (ʌ). The spelling of the word follows typical English spelling conventions for words with similar sounds, such as "rosebud" and "wristwatch". So, although the spelling may seem unusual, it is consistent with English orthography.
