Pronunciation: [ˈe͡ɪt ɪn tuː] (IPA) 
The spelling of the phrase "ate in to" is a bit tricky due to the use of the preposition "in." The correct way to spell it is with a space between "ate" and "in," creating two separate words. Phonetically, "ate" is pronounced /eɪt/ and "in" is pronounced /ɪn/. When combined, it can sound like "eyt-ihn." Remembering to use a space between the two words will ensure that the phrase is spelled correctly in written form.
