The phrase "doth impression of" is spelled using the traditional English spelling system, which can present challenges for learners due to its many irregularities. The /əʊ/ sound in "doth" is represented by the letter combination "do," while the /ɪmˈprɛʃ(ə)n/ sound in "impression" is spelled using a combination of letters that do not correspond directly to the individual sounds in the word. Despite these difficulties, mastery of English spelling is essential for effective communication and can be achieved through study and practice.
