The spelling of "wootten" can seem confusing at first, but it follows the basic rules of English phonetics. The IPA transcription for the word is /wʊtən/, which indicates that it is pronounced with a short "oo" sound, followed by a "t" and an unstressed "uh" sound. The spelling with double "o's" may seem unusual, but it reflects the fact that the sound in question is a distinct vowel sound in English, separate from the long "o" sound found in words like "boot" and "moon".
