The correct spelling for the phrase "study at prevent" is actually "study abroad program". The confusion may stem from the fact that "abroad" and "prevent" both contain the vowel sound /əˈ/. However, the two words have different stress patterns and different consonant sounds. "Abroad" is pronounced /əˈbrɔːd/, with stress on the first syllable and a rolled /r/ sound. "Prevent" is pronounced /prɪˈvent/, with stress on the second syllable and a soft /v/ sound. It is important to use correct spelling and pronunciation in written and spoken communication.
