The word "preilium" does not appear to be a recognized English word. However, assuming that it is intended to be spelled as "praedium," the phonetic transcription would be /'prɛːdiəm/. The IPA symbols represent the pronunciation of the syllables in the word. The apostrophe represents the primary stress on the first syllable, and the diacritic above the "ē" indicates a long vowel sound. The final syllable, "-ium," would likely be pronounced as /-iəm/.
