The spelling of the phrase "wast arrears" may seem odd at first glance, but it is actually a Scottish pronunciation of "westward." The IPA phonetic transcription would be /wɛst ərɪrz/. The "wast" spelling is a reflection of the way the "er" sound is pronounced in some Scottish dialects. "Arrears" is a commonly used term meaning outstanding payment or debts, but in this phrase it serves as a phonetic representation of the "-ward" suffix.
The phrase "wast arrears" seems to be a combination of two different words, each with its own etymology:
1. "Wast": The word "wast" is an archaic form of the word "waste", which can be traced back to the Old English word "wǣst" or "wēsten". The term originally referred to a desolate or uncultivated piece of land. Over time, its meaning expanded to include the concept of destruction, loss, or squandering.
2. "Arrears": The word "arrears" comes from the Old French term "arere", which means "behind" or "in arrear". It made its way into English during the Middle English period. "Arrears" refers to something that is overdue or unpaid, often in a financial context.
