Etymology

French, from Ancient Greek γλεῦκος ‎(gleûkos, “must, sweet wine”) related to γλυκύς ‎(glukús, “sweet”); note: -ose comes from glucose, not the other way round. In other words, the view of the word glucose as gluco- + -ose is a reanalysis rather than a historical etymology. This is unusual for being a reanalysis that works completely, that is, without any leftover nonsense syllables (such as the ham- in reanalyzed hamburger).

Pronunciation

  • (US) IPA(key): /ˈglukoʊs/
