The spelling of the word "wast regular" may appear confusing at first glance. However, it is simply an archaic form of the phrase "was regular". The pronunciation of the word "wast" is /wɑːst/, which is the past tense of the verb "be". The pronunciation of "regular" is /ˈrɛɡjʊlər/. This phrase was commonly used in older forms of English but has since been replaced with the modern "was regular".
