Seriously though, I know there is no right or wrong, just cultures but "vit-a-min" (vit rhyming with bit) for vitamin , "al-loo-minium" for aluminum and "let-toos" for lettuce is like fingernails on a chalkboard. lol
The origin behind Aluminum and Aluminium is kinda interesting because the inventor that first refined the element used both pronunciations and iirc I believe I he had even a third pronunciation ("alumium")that never caught on.
