The correct spelling of the word "hast shakes" is actually "has shakes." The word "has" is pronounced /hæz/ in IPA phonetic transcription, while "shakes" is pronounced /ʃeɪks/. The spelling error likely occurred due to confusion with old English, where the second person singular present tense of "have" was "hast." However, in modern English, the correct form is "have" or "has" depending on the subject. It's important to pay attention to spelling and phonetic pronunciation in order to communicate clearly and effectively.
