The spelling of the word "put dukes" is a tricky one because it is actually a colloquialism for "put up your fists" in British English. The pronunciation is /pʊt djʊks/ with emphasis on the "u" in "put" and the "u" in "dukes" pronounced as a "oo" sound. The "dj" sound in "dukes" is a combination of a "d" and a "j" sound, representing the "tsh" sound in the word. Remember to be careful with your spelling and context when using slang words like "put dukes".
