The phrase "wast displayed" is an archaic way of saying "was displayed". The spelling of "wast" is an old form of the past tense verb "was" that is no longer used in modern English. It is pronounced as /wɑst/ in IPA phonetic transcription, with a long "a" sound. The word "displayed" is spelled phonetically as /dɪsˈpleɪd/, with the stress on the second syllable. Despite its outdated usage, "wast displayed" can still be seen in literature and historical texts.
The phrase "wast displayed" seems to be a combination of two words: "wast" and "displayed".
1. "Wast" is the past tense of the verb "be" in the second person singular form in Old English. It is derived from the Old English word "wǣre" which meant "were" (as in "you were"). Over time, "wǣre" evolved into "wast".
2. "Displayed" is the past participle form of the verb "display". The word "display" is derived from the Old French word "despleier", meaning "to unfold" or "to spread out".
So, when combined together, "wast displayed" could essentially mean "you were unfolded" or "you were spread out".
