Swinbyrn is a word that appears to be of Old English origin. Its spelling can be phonetically transcribed using the International Phonetic Alphabet as /ˈswɪnbɜːrn/, where the initial "sw" represents a voiceless labialized velar approximant, followed by a short "i" vowel sound. The "n" consonant is nasalized and the "b" sound is pronounced using both lips. The final "yrn" syllable features a syllabic "r" and a long "e" sound.
