The correct spelling of the phrase "wast adjunct of" is related to its pronunciation. The word "wast" is pronounced as /wɑst/, which means "was" in the archaic form of English. "Adjunct" is pronounced as /ˈædʒʌŋkt/, meaning "something joined or added to another thing, but not essentially a part of it." Therefore, "wast adjunct of" means "something that was added or joined to another thing." Paying attention to the phonetic transcription can help in understanding the spelling of this phrase.
