The spelling of the word "Buitron" is not indicative of its pronunciation: it is pronounced as /bu:tɾon/, with the emphasis on the first syllable. The "ui" combination is pronounced as a long "u", rather than as two separate vowels, as in the word "fruit". The "t" and "r" sounds are pronounced separately, with a quick tap of the tongue between them. Although the spelling may seem confusing, it is necessary to memorize the correct pronunciation to avoid mispronunciation of the word.
