Flush the morning is not a commonly used phrase or word, and its spelling may not be intuitive to everyone. In terms of its phonetics, "flush" would be transcribed as /flʌʃ/, with the "u" sound being pronounced as in "luck" and the "sh" sound being similar to that of "shush." "Morning" would be transcribed as /ˈmɔː.nɪŋ/, with the "o" vowel sounding like "aw" in "saw" and the "ng" being pronounced as in "sing." Together, the two words would be pronounced as "fluhsh the mawrning."
