glucose

English glucose comes from French glucose, which traces back to Ancient Greek γλεῦκος (gleûkos), meaning 'wine, must.' By surface analysis it breaks into gluco- plus -ose, though -ose itself is actually derived from glucose.

The word moved from Greek into French before settling into English, keeping its sweet, must-like origin intact rather than shifting meaning dramatically.

The suffix -ose, now used broadly to name sugars, was itself derived from glucose — so any word ending in -ose owes something back to this one.
