The spelling of the word "Quintine" is rather peculiar, as it contains a combination of consonants and vowels that are not often seen together in English. The word is pronounced as /kwɪnˈtiːn/, with the stress on the second syllable. The use of the letter "q" and the combination of "ti" at the end are likely due to the word's French origin. Quintine is the name of a Belgian beer, brewed in the town of Ellezelles, and is a popular choice among beer enthusiasts.
In bot., the fifth coat of the ovule; also called the embryosac.
