The spelling of "Seak" may seem unusual, but it follows the rules of English phonetics. The first sound, represented by "s," is a voiceless alveolar fricative. The second sound, represented by "ea," is a diphthong commonly pronounced as /iː/ or /ɛə/. Finally, the last sound, represented by "k," is a voiceless velar stop. Therefore, the correct pronunciation of "Seak" would be /siːk/ or /sɛək/. While the spelling may be unique, the sounds come together to form a perfectly acceptable word.
