- glassful
- glassfulIn the plural, care should be taken to distinguish glassfuls from glasses full. A glassful is an amount contained in a glass, and three glassfuls (e.g. of water) means three times this amount, though not necessarily held in three glasses. Three glasses full (of water) means three different glasses each full of water. Note that there is no form glassesful. See also cupful.
