Pronunciation: [dˈɒst ˈə͡ʊvə] (IPA) 
The word "dost over" is often misspelled as "dust over." However, the correct spelling is "dost over," with an "o" as the second letter. The IPA phonetic transcription for "dost" is /dʌst/, with a short "u" sound. This word means "covered in dust," and is often used to describe objects or surfaces that have not been cleaned in some time. It is important to spell words correctly to avoid confusion and ensure clear communication.
The phrase "dost over" does not have a clear and established etymology, as it is not a commonly used or recognized phrase in English. I could not find any reliable sources or references that specifically discuss the etymology of "dost over".
However, "dost" is an archaic form of the verb "do" in Middle English, primarily used in the second person singular present tense. It is associated with Early Modern English and the works of William Shakespeare.
Without additional context or information, it is challenging to determine the precise meaning or origin of "dost over" as a whole phrase. It is possible that it may be a vernacular or regional expression, or it might be a variant or misspelling of another phrase or word.
