The spelling of the phrase "wast thrifty" is interestingly complex when looked at through the lens of the International Phonetic Alphabet (IPA). The first word, "wast," is pronounced /wɑst/, with the "w" sound at the beginning, followed by the open back unrounded vowel sound "ɑ" and a voiceless "s" at the end. The second word, "thrifty," is pronounced /ˈθrɪfti/, with the stressed syllable being "thrift" and ending with the "i" sound represented by "ɪ". The combination of these words creates a phrase that suggests someone who previously had been wasteful and is now working to be more thrifty.
