The spelling of the word "wast supported" may seem unusual to some, but it can be explained through its historical origins. "Wast" is an archaic form of "was" and "supported" is the past participle of "support". The IPA phonetic transcription of "wast" is /wɑːst/, while "supported" is transcribed as /səˈpɔːrtɪd/. Together, the pronunciation of "wast supported" would be /wɑːst səˈpɔːrtɪd/. While this construction is uncommon in modern English, it has been used historically and may still appear in older texts.
The term "wast supported" is not a standalone word in English. "Wast" is an archaic second-person singular past tense of the verb "be". It was commonly used in Middle English, but its usage has since become obsolete. On the other hand, "supported" is the past tense and past participle form of the verb "support", derived from the Latin word "supportare", which means "to carry from below" or "to sustain". However, "wast supported" is not a recognized term in modern English vocabulary.
