The phrase "wast seemly" may seem like an outdated and archaic spelling of "wasn't seemly," but it is actually a contraction of the Old English verb "wesan" (to be) and the adjective "sēmlic" (seemly). In IPA, the pronunciation is /wɑːst ˈsiːmli/. This phrase was commonly used in Middle English literature to mean "was becoming" or "was appropriate." Although modern speakers may not use this construction, it is important to understand the evolution of language and how meanings can shift over time.
The phrase "wast seemly" is not a commonly used phrase in English. It does not have a distinct etymology because it is a combination of two separate words: "wast" and "seemly".
"Wast" is an archaic form of the verb "to be" in the second person singular past tense. In modern English, it has been replaced by "were". "Seemly" is an adjective that means proper, appropriate, or fitting.
Combining these two words, "wast seemly" could possibly be interpreted as an old-fashioned or poetic way of saying "you were proper" or "you were appropriate".
However, it's worth noting that this phrase is not commonly used in modern English, so it may have limited usage and recognition.
