The correct spelling of the words "more invade" is /mɔr ɪnˈveɪd/. The first word, "more," is spelled as it sounds, with the /ɔr/ diphthong representing the vowel sound. The second word, "invade," is spelled with the letter combination "in" at the beginning, indicating a negative prefix, and the /veɪd/ ending representing the past tense form of the verb "invade." It is important to use correct spelling to ensure clear communication and avoid confusion.
