The spelling of the word "doest tests" may seem confusing at first, but it follows English's archaic second person singular present tense verb conjugation. When spoken aloud, it sounds like /dʌst tɛsts/. The use of "doest" instead of "does" indicates that the subject is singular and the present tense. This spelling is no longer commonly used in modern English and has been replaced with "does test." It is important to understand archaic spellings as they provide historical context for literature and language evolution.
