The spelling of "wast above" may seem unusual to some, but it is a correct archaic form of "was above." The word "wast" is the second person singular past tense of "be" in Middle English. The "a" in "above" is pronounced as a long "o" sound, represented in IPA phonetic transcription as /əˈbʌv/. Although this spelling is no longer commonly used today, it can still be found in some literary works as a way to reflect a specific time period or style.
The phrase "wast above" appears to be a combination of two words: "wast" and "above".
The word "wast" is the second person singular past tense of the verb "to be" in Middle English. It was commonly used during the medieval period. In modern English, this verb is now conjugated as "were" for the second person singular.
The word "above" comes from the Old English word "abufan" which means "on top of" or "over". It has remained relatively unchanged in its meaning over time.
So, when "wast above" is combined, it can be interpreted as an archaic expression meaning "you were above" or "you were over".
