The spelling of the word "wast wounded" may seem confusing, but it is actually a grammatically correct phrase from Early Modern English. The word "wast" is an archaic form of the second person singular past tense of "be". Meanwhile, "wounded" is the past participle of "wound". In IPA phonetic transcription, "wast" would be pronounced as /wɑst/ and "wounded" would be pronounced as /ˈwʊn.dɪd/. So, "wast wounded" would be pronounced as /wɑst ˈwʊn.dɪd/. This phrase is an example of how language has evolved over time, and how spellings have changed to reflect these shifts.
The phrase "wast wounded" is not a standalone word, but a combination of two words: "wast" is the archaic past tense of the verb "to be" in the second person singular ("you were"), and "wounded" is the past participle of the verb "to wound", meaning to do physical harm to someone.
The etymology of the word "wound" can be traced back to the Old English word "wund", which had a similar meaning. It is derived from the Proto-Germanic word "*wundō", which meant "wound" or "injury". The word has cognates in other Germanic languages, such as Old High German "wunta" and Old Norse "und". These ultimately stem from the Proto-Indo-European root "*wen-", which meant "to beat" or "to wound".
