"Wast bowed" is not a correctly spelled word in English. It is possible that it is meant to be "was bowed," which would be pronounced /wɑz baʊd/ in IPA phonetic transcription. The first sound, /wɑz/, represents the past tense of the verb "to be." The second sound, /baʊd/, represents the past tense of the verb "to bow," which means to bend forward at the waist as a sign of respect or submission. In summary, "was bowed" is the correct spelling and pronunciation of this phrase.
The phrase "wast bowed" seems to be a combination of two separate words: "wast" and "bowed". Here's the etymology of each:
1. Wast: The word "wast" is the archaic second person singular form of the verb "be", specifically used in earlier forms of English. It is derived from Old English "wǣre/wǣrest". Over time, this form of the verb was replaced by "were/arest" in English, and "wast" fell out of common usage. The meaning of "wast" in this context is equivalent to "were" or "are".
2. Bowed: The word "bowed" comes from the verb "bow". Its etymology traces back to Middle English, where it was spelled as "bowen". It ultimately derives from the Old English word "būgan".
