The spelling of the word "wast limbo" can be confusing due to its archaic and unusual structure. In IPA phonetic transcription, it is written as /wɑst ˈlɪmboʊ/. The first part, "wast," is an Old English form of "was" and is pronounced as "wahst." The second part, "limbo," is a Latin term that refers to a lower level of Hell and is pronounced as "lim-boh." Together, the phrase creates a unique and archaic expression that is rarely used in modern English.
