Brian is a male given name pronounced as a single-syllable or two nearly fused syllables in many dialects, typically /ˈbraɪ.ən/ or /ˈbraɪn/ with a light schwa in some rapid speech. It functions as a proper noun in English, used to identify an individual. In casual speech, the vowel sequence can sound like a long “eye” followed by a soft, reduced vowel. Emphasis commonly lands on the first syllable.
