How Do You Spell THIRTYEIGHTS?
Pronunciation: [θˌɜːtɪˈe͡ɪts] (IPA) 
The word "thirtyeights" is not a correct spelling in English. Its correct form is "thirty-eights," with a hyphen between "thirty" and "eights." This is due to the fact that the number "thirty-eight" is composed of two words, and when it is pluralized, an "s" is added to the end of the second word. The correct phonetic transcription for "thirty-eights" would be /ˈθərti-ˈeɪts/, with stress on the first syllable of both words.
