How Do You Spell GLASSIER?
Pronunciation: [ɡlˈasɪə] (IPA) 
The word "glassier" is spelled with two S's in the middle despite its pronunciation with a single "s" sound. This spelling follows the rule that when two vowels are separated by a single consonant, the consonant is usually doubled in English. In IPA phonetic transcription, the pronunciation of "glassier" is /ˈɡlæsiər/ with a short "a" sound, a "z" sound in place of the double "ss," and a "y" sound at the end.
