I decided to do more research, and it seems the -tuple suffix may have actually come from the word quintuple.

1863, word-forming element abstracted from quintuple, etc.

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)
- qbrass 8y agoThe 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.
