The word "YREST" may seem like a nonsensical collection of letters, but it actually follows the rules of the English language. In IPA phonetic transcription, it would be written as /aɪ'rest/ which breaks down to the sound of "eye" (aɪ) followed by "rest" (rɛst). This phonetic transcription accurately represents the pronunciation of the word, which is typically pronounced as "eye-rest". While uncommon, this spelling is still a valid way of writing the word "rest" when preceded by "eye".
