Tuple, duple, and Quadruple sounds like "oo-ple." Triple has a short "i" sound. Every-other "-ple" sounds like "tuh-ple"

  I decided to do more research, and it seems the -tuple suffix may have actually come from the word quintuple. > -tuple 1863, word-forming element abstracted from quintuple, etc. (from https://www.etymonline.com/word/-tuple https://www.etymonline.com/word/-tuple) A dictionary agrees: > Origin and Etymology of -tuple quintuple, sextuple (from https://www.merriam-webster.com/dictionary/-tuple https://www.merriam-webster.com/dictionary/-tuple) But then the pronunciation of quadruple can go either way. Although the "oo" is listed first, so is probably more common, I guess any of them would be considered OK: > \ kwin-ˈtü-pəl , -ˈtyü- , -ˈtə- ; ˈkwin-tə- \ (from https://www.merriam-webster.com/dictionary/quintuple https://www.merriam-webster.com/dictionary/quintuple)

    The dictionaries seem to attribute the words to Latin, while the -oo sound seems to come from Greek. The root word of both coming from a word for fold, "-plus" in Latin and "-plos" or "-ploos" in Greek. Greek and Latin have been mixed up enough over the years that it should be acceptable to use either pronunciation regardless of the true origin of the word.
