The phrase "doest credit to" is often used to describe someone who has done something well or praiseworthy. The word "doest" is an archaic form of the verb "does," which has largely fallen out of use in modern English. The spelling is based on the Middle English pronunciation of the word, which is transcribed in IPA as "dʊst." When spelled with the modern spelling of "does," the phrase would read "does credit to." Despite its archaic spelling, the phrase remains in use today as a way to praise someone's accomplishments.
