Pronunciation: [wɒst djˈuː] (IPA) 
The correct spelling of the word "wast due" is actually "was due" in modern English. The "t" at the end of "wast" is an archaic spelling of the past tense of "to be," which has since been simplified to "was." The pronunciation of "was" is /wʌz/ in IPA phonetic transcription, with a short "u" sound followed by a voiced "z" sound. "Due" is pronounced /djuː/ in IPA, with a "d" sound followed by a long "u" sound.
"Wast due" is an archaic phrase derived from Middle English and primarily used in the past tense. The term combines two words, "wast" and "due," both of which have independent meanings.
"Wast" is the second person singular past tense of the verb "to be" (used with "thou" in Middle English). It indicates a state of existence or identity in the past. For example, "thou wast" means "you were." In modern English, "wast" has been replaced with "were" in most contexts.
"Due" means something that is owed or owed as a result of obligations or commitments. It refers to that which is deserved, expected, or rightful. The term implies a sense of entitlement or responsibility. For instance, when something is "due," it indicates it is the appropriate time for it to happen or be received.
When combined, "wast due" suggests something that was deserved or expected in the past. It may refer to an obligation or entitlement that was unpaid, unmet, or not fulfilled at a specific point in time. The phrase points to an unfulfilled responsibility or an unpaid debt from the past.
Overall, "wast due" is a dilapidated phrasing that conveys the meaning of unfulfilled obligations or unpaid debts in a bygone era.
