Pronunciation: [wˈɜːt djˈuː] (IPA) 
The spelling of the word "wert due" can be a bit tricky. It is actually a contraction of two words: "were" and "it". When spoken, the "r" in "were" is pronounced, but when contracted, it disappears from the spelling. Additionally, the "t" in "it" is pronounced as a glottal stop (represented by the symbol /ʔ/ in IPA) in many English dialects. So the correct IPA transcription of "wert due" is /wɜrʔdu/.
"Wert due" is a phrase derived from Old English, wherein "wert" is the second-person singular past tense of the verb "to be" (were), and "due" refers to a state of obligation or a requirement. The term is an archaic construction that is no longer commonly used in modern English.
The phrase "wert due" implies that something should or ought to have been given or allocated to a particular person or entity based on a predetermined or expected standard. It suggests that the designated recipient is entitled to a specific item, response, action, or outcome as a result of an agreement, commitment, or customary practice.
The usage of "wert due" often implies a sense of justice or fairness, suggesting that the owed entity has a legitimate claim or right to the item or action in question. It signifies that expectations have not been met, and a debt or obligation remains outstanding.
While "wert due" has become archaic, variations of this phrase can still be found in legal or contractual contexts to denote the fact that a party has not received what was owed or promised to them. It can also be used to express a sense of disappointment or dissatisfaction when someone does not receive the treatment or recognition they believe they deserve.
The phrase "wert due" appears to be a combination of two words, "wert" and "due", both of which have separate etymologies.
1. "Wert": "Wert" is an archaic form of the verb "to be" in the second person singular. It is the form used for the past tense of "be" in the context of the second person. The etymology of "wert" traces back to the Old English word "wǣre/wǣreð" which means "was" or "were". This Old English word derived from the Proto-Germanic language, and over time, "wǣreð" transformed into "wert" in Middle English.
2. "Due": The word "due" comes from the Latin word "dūrus", meaning "hard" or "heavy".
