The spelling of the phrase "Is Life Party" reflects English pronunciation rules. In IPA phonetic transcription, it would be written as /ɪz laɪf ˈpɑːrti/. The "s" at the end of "is" indicates that it is in the third person singular form of the present tense. The stress is on the second syllable of "life" to create a two-syllable word instead of a single syllable. The stress also falls on the first syllable of "party" to emphasize the idea of a celebration or festivity.
