Pronunciation: [wɒst kənvˈʌlzd] (IPA) 
The correct spelling of the phrase "wast convulsed" is actually "wast thou convulsed". The use of "thou" in this phrase indicates that it is written in Early Modern English, which was spoken from the 15th to the 17th century. In terms of phonetics, the "wast" is pronounced as /wɑːst/ and "thou" as /ðaʊ/. The word "convulsed" is pronounced as /kənˈvʌlsd/ and means to be shaken violently with irregular movements.
"Wast convulsed" is an antiquated phrase that combines the archaic verb "wast," which is the second person singular past tense of "be" in Middle English, and the verb "convulsed." "Convulsed" is the past tense and past participle form of "convulse," which means to undergo violent, involuntary contractions or spasms. Therefore, "wast convulsed" can be understood as an archaic manner of expressing that someone or something was experiencing intense and uncontrollable bodily movements or spasms in the past.
The phrase "wast convulsed" is reminiscent of old literary or poetic language, particularly from the Middle English period. It might be encountered in works from the 19th century or earlier, but it is unlikely to be commonly used in modern English language or contemporary literature. Instead, present-day English would more commonly employ phrases like "were convulsed" or "experienced convulsions" to express similar concepts. It is important to note that the phrase's antiquated nature may make it difficult to fully comprehend for individuals not accustomed to reading historical or literary texts.
The phrase "wast convulsed" is not a single word but rather a combination of two words, "wast" and "convulsed". Here is the etymology of each word:
1. "Wast": This is the archaic or poetic form of the second person singular past tense of the verb "to be" in English. It can also be found in some dialects or older texts. The word "wast" comes from the Old English word "wǣre/wǣron", which means "were/was". It is related to the Middle English word "wast" and later evolved into the modern English word "were".
2. "Convulsed": This word is derived from the Latin verb "convulsus", which means "to shake violently" or "to shudder".
