The spelling of "wert valid" might seem a little odd, but it is actually an archaic form of the phrase "were valid." In IPA phonetic transcription, it would be /wɜr ˈvælɪd/. In modern English, we would say "were valid," but in Shakespearean English and other older forms of the language, "wert" was used as the second person singular past tense form of "to be" (similar to "you were valid"). While this spelling may seem strange today, it was commonly used in the past.
The phrase "wert valid" is an archaic construction that consists of two words: "wert" and "valid". "Wert" is derived from the verb "be" in its past tense form when used with the pronoun "thou" in Early Modern English. It is an obsolete conjugation that means "were" or "was". On the other hand, "valid" is an adjective that describes something as legally or factually justifiable, sound, or cogent.
When combined, "wert valid" refers to a condition or state of being in which something was or were justifiable, sound, or cogent in the past. It implies that a particular object, situation, or statement had legitimacy or correctness at some point in time, although it may no longer maintain that status in the present. It suggests that the concept or idea had a sufficient or acceptable foundation, reasoning, or evidence in accordance with established principles, criteria, or norms.
This archaic phrase is rarely used in contemporary language but can be found in texts or historical documents from the past. As language evolves, the phrase "wert valid" has largely fallen out of common usage and has been replaced by more modern expressions that convey the same meaning. It is important to note that this phrase may be unfamiliar or confusing to contemporary English speakers due to its antiquity.
