The phrase consists of the following Japanese words:

• ミセス (Mrs.)
• 大切 (important)
• な (a particle used to connect adjectives to nouns)
• お知らせ (notice, announcement)
• 何 (what)

When translated with the entire phrase intact to keep meaning clear, it would be: "[ミセス 大切な お知らせ 何](javascript:void(0))" This translates to "Mrs. Important announcement What" or more naturally in English, "What is Mrs.'s important announcement?"
