The correct spelling of the phrase "wast accessible" is actually "wasn't accessible". The IPA phonetic transcription of this would be /ˈwɑːznt əkˈsɛsəbl/. The word "wasn't" is a contraction of "was not," and the correct spelling reflects that. The mistake in spelling could be due to a lack of familiarity with contractions or typing errors. It is important to pay attention to correct spelling and grammar to ensure effective communication.
