It's unlikely that the word "chempaduk" exists in any language, as there are no results on search engines, dictionaries, or other resources. Without context, it's difficult to determine the origin or intended meaning of the term. However, breaking down the spelling using IPA phonetics, "chem" could represent a "kem" or "kəm" sound, "pa" could be pronounced "pə", and "duk" could be "dʌk". Overall, this would result in something like "kem-puh-duhk" or "kəm-puh-dʌk".
