The spelling of the word "duprey" can be traced back to its French origin. In IPA phonetic transcription, the word is pronounced as /duːˈpreɪ/. The "dup" sound is similar to "doop" with a slightly longer "u" sound. The "r" sound is present but not emphasized. The "ey" at the end is pronounced as "ay" like in the word day. While the spelling of this word may seem confusing at first, understanding its pronunciation can help improve spelling accuracy.
