Pronunciation: [wɒst ɐdvˈa͡ɪzd] (IPA) 
The correct spelling of the phrase "wast advised" should be "wert advised." "Wast" is actually an archaic form of the verb "to be" in the second person singular past tense. In modern English, we use "were" instead of "wast." "Wert" is an archaic form of the same verb in the second person singular past subjunctive tense. The correct pronunciation of "wert advised" in IPA phonetic transcription is /wərt ədˈvaɪzd/
"Wast advised" is an archaic term that originates from Middle English. It consists of two parts, the verb "wast" and the adjective "advised." The word "wast" is the second-person singular form of the verb "to be" in the past tense, suggesting "you were" or "thou wast" in old English usage. The term "advised" is used here as an adjective, meaning "having received guidance or counsel."
When put together, "wast advised" implies a past condition or state of being where the subject had received counsel or guidance. It suggests that the individual was previously advised or counseled about something.
However, it is essential to note that this phrase is no longer commonly used in contemporary English. It belongs to an older form of the language, specifically from around the 13th to 15th centuries. Nowadays, "wast advised" is considered an archaic expression and is not part of modern English vocabulary.
Due to its outdated usage, "wast advised" may be encountered in historical literature, old texts, or when studying Middle English language and literature. Its presence in these contexts allows for an understanding of the language and communication styles of the period in which it was commonly used.
The phrase "wast advised" is not a word with a specific etymology. It is a combination of the word "wast", which is the second person singular past tense of the verb "be" in Old and Middle English, and "advised", which is the past participle of the verb "advise". This phrase, when taken together, essentially means "you were instructed or counseled". The etymology of the individual words is as follows:
1. "Wast":
- Old English: wǣre or wǣs (past tense of "be")
- Middle English: was (past tense of "be")
2.
